Clock,date and time acting up

When i booted up this morning i got a message that said
your computers clock is set to a date before march 24th 2001. This may cause some applications to behave erratically.
please use the date and time prefrences panel to set the clock manually.
the clock is set to the correct time. Some apps are freezeing.
what do i do.

Mention "clock reset to wrong year" to a room of Mac users, and you'll get a room of people telling you to replace the PRAM battery. Do you have your Mac set to auto-sync with a time server in System Preferences> Date&Time? That could mask a failing PRAM battery once startup is complete. The G4 mirrored drive door models take a 3.6v 1/2AA lithium PRAM battery (see Macintosh Family: Batteries and Part Numbers, Part 2); that battery is commonly a stock item at places like RadioShack for around US$11 retail. You can find it cheaper online (e.g., here), although after adding s/h you'll likely be close to the retail price again. The owners manual for your Mac will show how to replace the PRAM battery.
p.s. I see Allan types faster than I!

Error: 0271: Real Time Clock Error - Check Date and Time settings.

Hello all,
I have lenovo T430s laptop that is configured with Bitlocker encruptions and TPM PIN entry. I don't think that has anything to do with the error msg I am getting but here it is. Error: 0271: Real Time Clock Error - Check Date and Time settings.
Press Esc to continue or F1 to enter setup. I am unable to get into BIOS or even the login screen for Windows 7.
Any advice would be appreciated.

Thanks to everyone for the help. Just want to close this out. I had a IBM/Lenovo technician here today and he replaced the CMOS battery. Upon the change, the computer is fine being reconnected to the dock (the three times I tried it). So it has been resolved with the battery. Surprised by the incompatibility claim because I am not having issues now. Wondering if it's just a USB 2.0 vs. 3.0 thing (and Lenovo trying to sell more peripherals, of course).
Thanks!

Getting an error message: "if you are here, it is probably because your computer's clock is wrong." Ergo, I can't get to the page I need. My clock's date and time are right. After re-booting, went to wrong time zone, which I changed-- still getting msg

'Requires=network.target' wasn't in it so I added it but nothing's changed. I've left it in because openVPN does require network.
As I said, I had this problem with a script so I don't think it's anything specific to openVPN. I had a weird occurrence this morning however. When I started the computer up this morning openVPN worked just fine. However when the computer rebooted openVPN couldn't resolve the host address again.

Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad

Hello everybody,
Can help anyone to resolve my problem.
I have an Thinkpad W520 (42823FG), BIOS 8BET60WW 1.4 When I disconect AC power and remove battery and connect again, I see this message on screen:
"Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad
Press Esc to continue or F1 to enter Setup"
Is this a system board problem or CMOS battery problem ?
Thank you

Hello and welcome,
It's probably (hopefully) just the CMOS battery. The easiest way to find out is to just replace that battery.
Page 85 of the Hardware Maintenance Manual:
Hardware Maintenance Manual
Here's an example of the battery. I'm not recommending (or not) this vendor:

My laptop died last night and the date and time was set for 1/1/2000. I went to change the date and time and cannot. For some reason when i pull up system preferences it will not load date and time but will load other stuff. Please help.

Last night my laptop died and the time and date was reset. I cannot acess date and time preferences to change it and my laptop is acting really weird. My CD drive is broken so there are no options to put in a cd. Please someone help i need my laptop for school and cannot afford another.

Many system actions will misbehave, given an inaccurate date. Resetting the NVRAM and / or SMC will not fix it, and if the system has a preposterous date you may not be able to open System Preferences to correct it. This dilemma may or may not be addressed in a future OS X update.
If you cannot open System Preferences you can reset your system date and time using Terminal.
Please read everything that follows before proceeding. Write them down if necessary because the effects of setting a preposterous system date are unpredictable.
Quit System Preferences, force quit if necessary: OS X: How to quit an unresponsive application using Force Quit
Open Terminal - it is in your Utilities folder and looks like this
You can find Terminal by using the Finder's Go menu and choosing Utilities, then double-click the Terminal icon.
At the prompt, you will be typing a command resembling the following:
sudo date mmddhhnnyyyy
... but you must substitute the actual date and time in the command that corresponds to the date format used for your location. In other words if your custom is to use a date like 8 February 2014 then reverse the mm and dd values.
Substitute numerals in the above command according to the following:
mm = month
dd = date
hh = hour (24 hour format)
nn = minutes past the hour
yyyy = year
Each of those values must be two digits except for the year which can be two or four digits. As an example if the current date and time is February 8, 2014 at 9 PM your command will be the following:
sudo date 020821002014
or
sudo date 0208210014
Either one will work. If you enter nonsensical values the system will attempt to parse the entry correctly.
To recover from your inability to use System Preferences to set the date and time, the value entered does not have to be precise, it just has to be approximate.
Enter that command using the actual time and date for your location and in the appropriate format, then press the Return key. Terminal will ask for your Admin Password - the same one you use when you log in to your Mac. Type it and then press the Return key. What you type will not appear, not even with •••• characters.
To determine if your change was effective just type the date command and press the Return key. Terminal will reply with the date and time. If it appears correct and in the correct format, you should be able to open System Preferences > Date & Time once again. Selecting the "Set time and date automatically" and choosing an appropriate time server will adjust your Mac's system clock to the precise time.

Getting Date and Time to Show in the Menu Bar

I have the OS setup to set the date and time automatically and the clock set to "show date and time in the Menu Bar. I have the international set up for the Day of Week, Month, Date and Year, but the menu bar only shows "Fri X:XX:XX PM" is there any way to get it to show me Fri May XX, 2008 X:XX:XX PM"?
Thanks for any help.

I use iClock too. It is much more customizable than the Time & Date clock provided with the system. I have used it for several years and it has been very stable for a third-party application.
Although I have only used it for a couple of months, I also really like another third-party application you may like, to put weather conditions on the menubar called WeatherDock (freeware). It accesses Weather.com to provide the current temperature (of course) but it can include several other weather conditions (depending on how much space you have on your menubar). In addition to temperature, I have it show the weather condition (currently partly cloudy, typical in Houston), wind direction and speed (I ride a bike to the office and this tells me if I’ll be fighting it or aided), and humidity (also a Houston favorite). It will also speak the weather conditions when they change.

Bizarre date and time hang.. Hardware or software?

Hi all, i have this totally bizarre problem that i have never seen in my 25 years of using mac's..
Since yesterday my date and time seems to hang; it doesn't really update anymore and when i hover my mouse over i get the beach ball. Also this seems to effect the system prefs, if i start that up it sometimes hangs too.. which then effects and hangs the finder.
Last night i deleted the associated plist and cages things, zapped the pram etc, no luck with this. Also disk utility showed no problems with my drive.
So today i installed a fresh new 10.6 system which did install, but the first 2 attempts getting across the welcome&register screens gave me beachballs and complete unresponsiveness too. So now after some hard restarts i'm puzzled.. Also startup and shutdown seems slow.
As far as i can tell there is no special clock battery in these things that could cause this? So anyone any ideas? Every idea is much appreciated!
Thanks, Gerben

Welcome to Apple Discussions Gerben.
Your computer is apparently early 2008. Do you have the extended Applecare warranty? If you do you could take it to the nearest Apple-authorised service centre & get it checked out.
If not, try starting in safe mode by holding the shift key until the Apple logo appears. See whether the problem is still there. If not, it's a software problem almost certainly.
However you should also disconnect all peripherals and see whether there is still a problem. If not, then it is likely one of the peripherals is the source of the problem.
Failing this insert your original installation dvd, disconnect all peripherals and restart holding the D key. This will check hardware. If any errors are reported you might need to approach service.

Adjusting date and time does not work for pictures from one camera.

I have a set of pictures taken with a Casio EX-Z20 camera in my Aperture 2 library. Because the clock of this camera was off by a few hours I changed them all at once with the option "Adjust date and time...". This worked well and when I sorted the images from different cameras by date in Aperture they were in the order.
When exporting all the images as JPEG the images in the set from this camera was reset to it's original.
That was very strange, I decided to try and change the date of these images in the master files as well by checking the checkbox "Also change master files".
When I change the date from 15-10-2008 18:34:44 to 16-10-2008 10:34:44 (+16 hours) the date of the image changes to 16-10-08 01:36:43 GMT+02.00 (+9 hours, 1 minute, 59 seconds).
When I change the date from 16-10-08 01:36:43 to 16-10-2008 19:36:43 (+18 hours) it ends up as being 16-10-08 10:38:42 (+9 hours, 1 minute, 59 seconds)
When I change the date from 16-10-08 10:38:42 to 16-10-08 10:48:42 (+10 minutes) it ends up as 16-10-08 01:50:49 GMT+02:00 (-8 hours, 47 minutes, 7 seconds)
I have worked around this problem by adding some hours to the desired time and eventually got it about right, but this is still a very annoying problem. Has anyone else encountered it or know of a way to avoid it?

I certainly have had issues regarding wrong dates, time stamping and DNG's in Aperture. There have been posts here from others as well with the same kind of date problems.
I have reported the bug to Apple and hope for a solution to the issue in a near future.

Wrote the current Date and Time in the backend

HI everyone,
I created a table view, where I display several records. Right now I will add an record to this table, which should be written back in the backend and automaticaly add the current date and time.
But I don´t know to make this. I tried several time with the funktion "now()", but it doesn´t work. So any help for me, to explain how I can display the actual time and then write it back to the backend?
Thanks

we use a crm system. but the BAPI I mentioned was
just to play with. My basis will develop a new API
for the project, that have the requested Inputfields.
But what I tottaly forget was, that there has to be a
field for the time, so thanks for the advice.
No Problem.
I´m still of the opinion , that it should be possible
to add the curret time in a field with the
funcionality of the VC, even there is a way to show a
clock with the current time. My problem is that I
can´t figuer out how to do this.
Therefore you can use the TNow() function (Time functions) and the Now() Function (Date functions). You can cast them to a string and concatenate the string, then you have the date of today with the current time. This string you can format and transfer it as input for your BAPI_ADD_BP for example.
Hope that helps.
Best Regards,
Marcel

How to detect the iPhone Date and Time

Hi guys,
I am new this plateform and I am working on an iPhone application in Objective-C. I need to detect the date and time of iphone clock in the objective-c.
Please let me know if anybody knows how can I do it.
Thanks,
Ranjit Singh

Ranjit,
Be sure to consult the docs for the iPhone SDK. If you are running the simulator, you probably have access to frameworks and classes not available on the phone itself. The iPhone docs don't show NSCalendarDate as a valid class for iPhone (but it exists for MacOS). I think you'll need to use NSCalendar if you wish to have it run on the device (and not just the simulator).
Do you have a device you are testing on? It would be good to verify this (I don't and therefore must use the simulator).
Cheers,
George

"RT Set date and time" does not set seconds in UTC mode

Hallo,
I tried to set the time on my cRio 9012 with the function settimeUTC which is used by the "Set Date and Time" vi. But the seconds I enter are ADDED to the current time and not set as new value.
Even the vi shows this behaviour: I set up a vi in which the time is set in a loop (100ms delay) and read again. When I set local time the clock stops (as expected) but when I set the UTC time the seconds keep on running...
Can anybody help me with that problem???
Thanks
Florian
Solved!
Go to Solution.

Hi Andreas,
well it does not matter if I set a time zone in the MAX or not. In my example I was working on UTC + 0 but even when I set it to my local time (UTC + 1) I get the same behaviour modified by one hour.
My LabView Version is 8.5. In in the MAX under Software-> LabView-RealTime it says that I am using 8.5.0.
I suspect that the settime.out which is installed on the cRio is probably the root of the problem as VxWorks itself does not offer a function (at least I did not find one) to convert from broken down system time to system time in seconds. There only exist one to convert from broken down local time to system time in seconds ( mktime() ). The reverse function is available for both cases: gmtime() and localtime(). I also did not find a way to find out the offset of the local time. So I have to use the library function settimeUTC() from settime.out.
As I offered I can send you the settime.out file from my cRio for reference or maybe you can tell me how to find out what the version of the file is. It seems not to be an ELF file as I looked inside it to find some timestamp or version info...
Thanks so far
Florian

Automatically Setting Date and Time - How often does it occur?

Can anyone tell me exactly when Mac OS X retrieves the date and time from Apple's time server? Quite often, the time on my Mac is several seconds out from the correct time. When I open the "Date and Time Preferences", it seems to sync up with the correct time and everything is good.
Is there any way to schedule when Mac OS X automatically sets the time, or how frequently over the course of a day it sets the time? Or, alternatively, does anyone know of a utility that I can use to accomplish this?
Thanks in advance for any help you can give me.

Hi Barry,
Thanks for your reply.
I have a wristwatch that receives a radio signal which transmits the correct date and time from an atomic clock in Fort Boulder, Colorado. The watch automatically picks up this signal three times a day (in the early morning so as to get the correct time once we go on/off DST) and sets my watch to it. So my watch is always accurate (so long as it can receive this signal). I have an alarm clock that uses the same principle. It's actually kinda nice...I can look at my watch and KNOW I have the right time!
At any rate, that's how I know my Mac's clock is out a few seconds...I just check it to my watch.
The real reason I would like to be able to schedule this function (or, at least have it occur more often) is so my Palm TX gets the correct time from my Mac each morning. I automatically sync it to my Mac every morning, and one of the conduits actually synchronizes the Palm clock to the one on my Mac.
I'm just curious to find out when exactly Mac OS X sets the clock. Does it happen once a day? Once a week? I haven't had my Mac for all that long, so I do not know what will happen when we go off DST this spring. Will OS X (based on the date) just bump up its clock by one hour, or will it actually get the correct time from Apple's time server and sync the Mac clock to it?
And, if there's no way the change when this happens or the frequency with which it occurs, is there anyone out there who has written a utility which can do this?
What about Automator? I'm new to the Mac world, so I am just learning about all this stuff. When I open the Date and Time System Preferences, the clock seems to sync up at that point. Could I use Automator to do this?
As always, any help would be most appreciated.
Thanks again for your reply, Barry!

Automatically setting date and time

Is there any way to automatically set the date and time on an iPod Touch? I don't think so, but I thought maybe there was a third-party app or some other work around to do this. I don't see why this isn't built into the OS. I know the iPhone can do this by getting time information from the cellular network, but why cannot this be done also over a wireless network? My computer can connect to a time server over the internet.

Set Date and Time Automatically...doesn't

We've noticed that the setting to automatically synchronize date and time to Apple's time server doesn't work if the system preference is 'locked'
In other words, if the user that's logged in currently, isn't an admin user, then the machine doesn't set the date and time automatically.
As soon as you unlock the system preference by clicking the padlock at the bottom, the date and time sync as they should.
Anyone else noticed this?

We do want the clock correct. The issue here is that the internal clocks drift - as I understand it, this is the one of the main reasons behind using a network time server.
With the Date and time preferences set to 'Set date and time automatically', the but with the lock at the bottom corner locked- it's as though being locked is preventing the automatic date and time settings from updating.
But the preference is checked on, and so the clock should be 'resetting' itself as necessary.
To give an example- say the machine has been off for a while, and unplugged. This will cause the machine not to know what the Date and Time is. When the machine starts up, the preference should kick in, and the machine should 'Update date and time' automatically.
But it doesn't. So long as that padlock is locked, even though the preference is checked on, the machine will not alter the date and time - until the padlock is unlocked.

Date and Time on Menu Bar

Up until now the date and time has been displayed on the menu bar as...
Tuesday, November 28, 2006 8:09 AM
Now, for some reason, it's being displayed as...
Tue 8:09 AM
Here's what I've tried in trying to restore the format...
1) System Preferences > Menu Bar Clock > Show Date and Time in Menu Bar
2) Deleted the following preference files:
com.apple.MenuBarClock.plist
com.apple.systempreferences.plist
com.apple.systemuiserver.plist
Does anyone know how I can restore the format?
Thanks!

It looks like there can be as little
as 6 or so characters between the two sets of
icons
That sounds low, especially in
the Finder, even at the lower screen resolutions. I
just played with stepping down resolutions on this
Mac, and various right-side icons (the CoreServices
eject.menu, Display, Classic, and sound icons, plus
those from MenuMeters) disappeared
before the date and time (shown as "Tue 28 Nov, 04:00
PM" were affected (right-side menu items are
truncated from left to right).
In my case, just the date disappeared. So instead of seeing...
Tue November 28, 2006 5:43 PM
...I was seeing...
Tue 5:43 PM
The icons to the left (on the right side icons) were still there and unaffected.
What Display
resolution do you normally use?
It's set at 1024 X 768.
Does the time&date
format go back to the expected form if you increase
resolution to maximum as a test? If the format
affected by starting up in Safe Mode?
After trying the remedy you reference in your previous post, the format is back to where it was so I won't be able to test it. But I guess you suspect that the Date and Time was truncated because there wasn't enough space between the left side and right side icons, is this right? It would seem like a logical explanation...
