NTP sets SMB clients to wrong time

Hi
The Server (Mac OS 10.6 server) is set as a time server for the domain but from yesterday reset most of the Windows clients that logged on via SMB to about 3/4s hr fast with the result that IP address's were dropped (Lease expired) and software relying on a network connection failed, time stamps of saved files were wrong and emails had the wrong time. In one case the month was changed to October so the guy went on holiday! Seriously, this is a big problem.
I've tried resetting the time locale, NTP time server and got rid of "LocalTime" which was a folder instead of a simlink but clients are still reporting time anomalies.
Thanks

ntp isn't particularly related to smb/cifs/samba, nor to dhcp, and ntp doesn't implement local time; ntp uses utc/gmt as the time base, and the local boxes adjust their time and timezones based on the client-local timezone definitions.
It could be that ntp is misconfigured, that something has gone seriously wacky with the ntp time base (hardware error? software error? network error? time-based attack? etc), or there's a rogue ntp server running.
Have a look at the ntp chatter in the system.log console log on the ntp server as a starting point, and at whatever passes for logging on the ntp clients, and at the settings for ntp. Out-of-the-box, there can be the requirement to tweak the ntp client or daemon configuration via the /etc/ntp.conf file, for instance.

My iphone 3gs has started showing the wrong time and date. All was fine until this afternoon when it changed. My apps have the right time and date. However the world clock is wrong. I have to turn off the automatic time setting to get the right time.

My iphone is showing the wrong time and date. All was well until sometime this afternoon when it changed... to Nov 5 (2 days prior to today), and about 9 hours and some minutes before the actual time. The world clock for my time zone shows the same wrong date and time. My calender shows the same wrong date and time. The phone can not find my time zone any more. The only fix I found was to turn off the automatic setting for time. What is happening? Ideas?

just sorted mine went to
settings-mail,contacts,calender-timezone support
then turned it off then on tapped time zone and typed london
this did sort mine

use a supported web browser to go to iCloud.com. Click your name (top right) and set you Time Zone to the correct one.
Hope this helps, Andrew

Hi. I'm trying to set-up the wireless access times in my Airport Utility. I need to enter the "Description" and the "MAC Address" of each wireless client before I assign access times. What are these? Thanks.

Hi. I'm trying to set-up the wireless access times in my Airport Utility. I need to enter the "Description" and the "MAC Address" of each wireless client before I assign access times. What are these? Thanks.

Let's say that an iPhone is one of the wireless clients that you want to allow access to the network.
The Description of this device is anything that you want to specify for easy identification purposes. For example, the Description might be something like......
Rex's iPhone
The MAC Address, also known as a Wi-Fi Address is a unique indentifiction number that is assigned to every device. The number will always follow this form:
xx : xx : xx : xx : xx : xx, where "x" could be a number or letter.
To find the MAC Address or Wi-Fi Address of an iPhone or iPad.....
On the Home screen.....
Tap Settings
Tap General
Tap About
Wi-Fi Address is the item that you want
If you have a Mac computer......you can find the MAC Address or Wi-Fi Address as follows:
Open System Preferences (gear icon on the dock)
Open Network
Click on Wi-Fi on the left
Click Advanced at the lower right
The Wi-Fi Address for the Mac is located at the bottom of the window
Other wireless devices usually have the MAC Address or Wi-Fi Address on the label on the back or bottom of the device

Wrong time when using java Calender

Hi All,
I have a Solaris 9 system. The Timezone for which is set to "TZ=Asia/Colombo". I have written a small java code to get the time using Calender class.
The problem is I get wrong time and wrong ZONE offset information
Output of the java code
bash$ java TimeFile
Tue Dec 18 12:53:28 LKT 2007
utcTimeZone ===sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
ZONE offset ===21600000 //Should be 19800000 Since the system is in UTC+5:30
DST offset ====0
System time details
bash$ date
Tue Dec 18 12:23:42 LKT 2007
bash$ date -u
Tue Dec 18 06:53:47 GMT 2007
The java version I am using is
bash$ java -version
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)
bash$
Below I have pasted the code
public class TimeFile
public static void main(String[] args)
Calendar currentDateNTime = Calendar.getInstance();
Date date = currentDateNTime.getTime();
System.out.println(date);
int offset = currentDateNTime.get(Calendar.ZONE_OFFSET);
int dstoffset = currentDateNTime.get(Calendar.DST_OFFSET);
TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
System.out.println("utcTimeZone ===" +utcTimeZone);
System.out.println();
System.out.println("ZONE offset ==="+offset);
System.out.println("DST offset ====" + dstoffset);
}

Perhaps you should update to a newer version of Java. If you have to stick with 1.4.2, then you should at least use 1.4.2_15.
See also http://java.sun.com/javase/timezones/tzdata_versions.html on information about how to update time zone information in Java. In 2006 there was an update to the timezone info also covering Sri Lanka.

Outlook Client recurring appointments time zone / GMT offset problem

I will try to describe this with text, although it's a very visual problem. I added a post to my blog with
it so I could include pictures. If you think you need pictures to understand the text below, please review that entry.  Please note, the one appointment instance cited below, is an example, there are many others with this same problem,
and it only happens with recurring appointments.
Relevant System Information:
Windows 7 Utlimate
Office 2010 Professional Plus (14.0.6023.1000 64-bit)
Exchange services hosted by Microsoft.
Android HTC Inspire 4G also configured as exchange active sync client.
Issue Description:
I have a specifications meeting that is scheduled for Tuesday mornings (every 2 weeks) at 8:30 am. In the body of the appointment, it even has this text spelled out. "When: Occurs every 2 weeks on Tuesday effective 11/23/2010 from 8:30
AM to 11:30 AM (UTC-05:00) Eastern Time (US & Canada)." as an indicator of the actual appointment time. The problem is that one day, several weeks after this appointment had been sent to me, Outlook 2010 decided that it was really at 1:30 PM.
Since that time it's been showing incorrectly on my calendar at 1:30 PM.   So, I recognized almost immediately that this was a 5 hour difference, which happens to also be my timezone offset (except that I'm currently in daylight savings time -- so
it's really a -4 offset right now).
I ran the 2010 service pack 1 installer, based on the suggestion of my IT group, and found I already had the service pack installed. I've tried the timezone tool as well and that didn't work. Please keep reading.
Next I went to my exchange host with outlook web access.   The appointment is closer to correct there, showing at 9:30am. It think here it almost seems as though it's applying the DST, but not correctly, maybe doubling it?.
Meanwhile, back in outlook, if I go to the scheduling assistant and look at my time while making an appointment with other invitees it - much to my surprise - matches the time in OWA, not the time in outlook client.
Finally, if I go to my Android and look at the appointment, it is correct. 8:30 AM.
So to summarize:
Real Appoinment:   8:30 AM
Outlook Client Time: 1:30 PM
OWA / Exchange Time: 9:30 AM
Android Calendar Time: 8:30 AM
This applies to many others, this is just a convenient example.
This applies only to recurring appointments.
Any help would be very appreciated.
Thanks,
Jon

Status Update, and recommended next steps:
I opened a ticket with HTC support the day before yesterday (Ticket # 03543601). The initial response was an email reply with the typical level one suggestion to remove and re-add the Exchange ActiveSync account on my phone, and if that didn't resolve the
issue to do a hard reset and then add the account again. Since I have multiple users experiencing this same issue, where the common denominator seems to be centralized around the move from Outlook 2007 to 2010 and the HTC Gingerbread OS, I convinced them that
this would not be an acceptable remedy, and my case was immediately escalated without hesitation. I will say that though I don't have a resolution, I'll applaud HTC for not giving me the runaround and giving me a live person who could talk intelligently about
the issue.
Today, I received a phone call back on this ticket from someone in the escalations department at HTC named Travis. After explaining the issue in detail to him and referencing
this specific thread, he acknowledged that it did in fact sound like a coding issue coming from the device where the value in the “dispidApptTZDefStartDisplay” property was being set improperly by the device/stock email/calendar application in their implementation
of ActiveSync. He then stated that he would relay this to the developers to look into the issue. He further elaborated that the case would either be in a status of, "this is being looked into", or "We believe this to be resolved in [x] update". He said that
they will probably continue releasing updates for the Incredible (I did not specifically ask about the Incredible 2), and while the Incredible 2 is definitely slated to get Ice Cream Sandwich, the Incredible one is still in a classification of, "being evaluated".
Personally, I doubt that the Inc 1 will get ICS, but it is possible. From what I have read, the general stance is that phones will be updated for 18 months after release, and the Inc 1 is 24 months old this month (bummer - I REALLY like this phone).
According to Verizon and HTC, these are the phones that will get ICS (or Android 4.0):
Ice Cream Sandwich Coming to Many Verizon Wireless Smartphones
Android 4.0, Ice Cream Sandwich Updates
While it is possible that an update will be released for the Incredible 1 to fix this issue, it will likely be months before one is available, so we'll probably have to move to Touchdown for Exchange by NitroDesk in order to resolve this issue....or move to
a newer phone with ICS 4.0.
Speaking of which, there is a whole laundry list of issues with Exchange ActiveSync and third-party devices. A number of them are listed in this Microsoft KB article:
Current issues with Microsoft Exchange ActiveSync and third-party devices
Per the article:
Microsoft's recommendation for Android - Upgrade to Android OS 4.0
Microsoft's recommendation for iPhone/iOS devices - Upgrade to iOS version 5
So, for anyone on Android experiencing this issue (or others listed in the Microsoft KB above), if your phone is likely to get ICS soon, then you may want to hold on and just be vigilant about checking your calendar on OWA. If your phone isn't slated to get
ICS or if you can't wait, my recommendation is to get Touchdown for $20. You may still have to delete and re-create appointments that are wrong, but hopefully the issue won't happen any more once you move to Touchdown. And if they do, at least you've got a
shot at a more rapid fix with a company like NitroDesk. (no offense HTC).
Good luck. I probably won't post again unless I get notice of a fix for this specific issue or some other significantly useful information.

Sysdate giving wrong time

When I log in to DB via the listener I get different time to when I log to DB direct (on the db box, set ORACLE_SID).
Say OS time is 15:00 and my TZ=GB for oracle user.
1. When I do sqlplus [email protected]
I get sysdate as 14:00
2. Set ORACLE_SID=DB01, Then do sqlplus user
I get sysdate as 15:00
My listener process has TZ=GB
Why when using TNS alias I get wrong time, is there a config for listener about time?
I think it is to do with, when Oracle lsnrctl hands off connection to client it is giving in GMT (since machine default is GMT).
I am reading on Oracle docs, its taking time.
Please help.

What version of Oracle is this happening with and are you running RAC? If you run RAC and use svrctl to start the database the utility fails to pick up the correct enviornment time zone information unless you set it in the utility with version 9.2.
The client session also has nls parameter for date and time zone information. The difference could be due to these settings also. Check out your .glogin file and your person .login file if you have one.

WINDOWS SERVER SYNCHS WRONG TIME!!

Hi guys,
The giving: we have a Hyper-v environment, [Hyper-v A] hosting [DC A] and [Hyper-v B] Hosting [DC B] now DC A & B are replicated and working fine, suddenly we found out that all client PC's synching with the DC's wrong time!!! going to DC A or B, we
found that Clock time is WRONG! its about an hour offset, the time on DC A & B is configured to sync from web
[Automatically Adjust Clock for Daylight Saving Time] but for some reason its synching a wrong time!! for the meantime we set the clock manually and cancelled the Auto Adjust, but for resolution what the deal!!?
HOW CAN WE FIX THIS!????
FYI MS CU didnt fix this even.
Thank you in advance.

Hello,
please see for time sync on the PDCEmulator

Wrong time on virtual machine

Hello,
I'm running Windows 2003 Standard virtual machines under a Windows 2008 Datacenter Hyper-V Server. The system time of all of my virtual machines is 3 hours later than the time of my physical host.
When I try to change the time on my VMs, it resets itself back to the wrong time after a few seconds, and I get this message in the System log:
Event Type: Information
Event Source: W32Time
Event Category: None
Event ID: 35
Description:
The time service is now synchronizing the system time with the time source VM IC Time Synchronization Provider.
Any ideas on what might be causing this?
Thanks,
Stephen

Are any of your DCs on physical boxes? If they are then set them up to pull time from pool.ntp.org. Then set up your hosts and guests to pull from that DC. Allow firewall exceptions for NTP inbound on that DC.
If all DCs are VMs then set up one of the physical hosts to poll pool.ntp.org for time and then set the VMs to poll the host. Again set the firewall accordingly.
http://blog.mpecsinc.ca/2011/01/hyper-v-preparing-high-load-vm-for-time.html
We have had a lot of pain over the time skew situation for VMs.
The above methods work for us. In some cases we drop in an HP MicroServer with Win2K8 R2 running as a DC and set it up to poll pool.ntp.org and then have all VMs poll it for time.
The problem has to do with the polling frequency needed as indicated in the blog post. Do that to ntp.org's servers and they will pass along the Kiss-Of-Death packets basically killing the ability to poll their servers for time.

Is my iPhone calendar reading from the wrong time zone? How do I fix it?

First, here is all the info that I have about all of the clocks on my phone: the date and time on my iPhone are set automatically to Vancouver's time zone, in the Clock app though, I've also added in the clocks for Seoul and Manila so that I know the time when I need to contact friends out there, etc. Location wise, everything else on my phone is fine: my map correctly shows where I am, the weather app shows the weather for my city and my clock changes automatically for daylight savings.
Now, when I put in an event into the calendar app, while putting in the details such as start and end time, the Time Zone slot is always set to Seoul for some reason. I have to go in and change it to Vancouver manually. Even after doing this and setting everything though, the alarm always goes off at the wrong date and time - I think it' s going off at when that time reaches Seoul, not Vancouver. So then I tried setting it again, this time, leaving the time zone as Seoul in case things were somehow just 'backward' in my phone, and still the alarm went off at the wrong date and time.
I really can't understand it and haven't got the faintest clue as to how to fix it. Any ideas??
In case this better or further explains what I'm trying to say:
I just opened a new event on my calendar. I set it to begin twenty minutes from now (5:20AM) and left the ending time as the default one hour later (6:20AM). I also did not change the time zone which is already reading Seoul for whatever reason. I hit done, I'm taken back to the main calendar page, and there it shows as it should: 5:20AM today. I then went to set second event for 5:15AM only this time, I changed the timezone to Vancouver. All the information looks correct, but this time, when I hit done and am taken to the main calendar page, that event is recorded as having been set to 21:15PM instead!!
[ I have an iPhone 4 but...I don't know what CDMA or GSM means so I'm not sure which pertains to me...]

The SMB client failed to resume a handle on a file share with continuous availability

Hi.
We have a 2-node WS2012 cluster that has a file server role with couple shares configured.
We're however constantly getting spammed by the following errors in the eventlog:
1) event 1002, source: SmbServer, message: "RKF failure - SRV2 failed to get acknowledgement from Resume Key filter for persistent handle request."
2) SCOM has an alert opened with this description: "SMB client failed to resume Continuously Available (CA) handle as Resume Key Filter is not acknowledging the handle." Per the alert knowledge, we've inspected ResumeKeyFilter eventlog, but it
contains only informational message and warnings and none of those are from the time the alert was created.

XFCE's Clock shows the wrong time...

XFCE's clock shows the wrong time constantly (it always shows the GMT time), but whenever I run hwclock -r, it tells me the correct time. Can anyone help fix it?

Well, I think I found what was wrong at last. It seems that the timezone wasn't set in the rc.conf, even though the TZ variable was set. I changed it, but will have to restart in a bit to see if it works.

Nano World time displaying wrong time!!

I just got hold of my ipod nano this morning. Was so looking forward to it till i found out later on that it wouldn't work with my 3rd party USB2 pci card. That was fine, i just used USB1.1 which took really really really long.
Finally, when it was done, i got to fiddling with it. I toggled to the World Clock and thought it'd be cool to fiddle with it. What i found was that the world clock is displaying all the WRONG times. I'm currently in Perth, Australia which is +8GMT. The ipod's main clock and date are all set correctly, and timezone set to Beijing, which is +8GMT equivalent.
But, when i get the world clock feature to display with my time, it displays 7AM (the real time is 3PM). It's the same with the other regions/times as well. Anybody else have this problem?
Hope somebody comes up with a fix
Thanks!

First, u pop the CD that came with the nano into your computer. Then, you locate the ipod software updater. Just launch that program, click and restore and follow the on scree instructions.
You should be good to go after that
