No 24 hour clock in Calendar?

I use a 24 hour clock in everything I do, but it seems to be unavailable in iCal. Is this the case, and if so, why?

Peter,
Quit Calendar, open System Preferences...>Language & Regions>Regions: and set/-re-set the appropriate Region. Also, make sure the "Time format:" in that preference pane is checked for 24-Hour Time.

Printing calendar with 12 hour clocks

I have my Mac set up with 24 hour clocks. I don't like having to remember which oxymoronic 12 am or 12 pm a computer uses.
But I need to print up calendars to share with people who seem to have troubles with this. It is obvious in reading whether an event is in morning or afternoon. Is there an easy way to print up a calendar using a different time default from my computer's default?
(I also can't trust what date midnight is).

Calendar is tied to your system preferences, you can switch it off just for printing.

UWC gui bug with 12/24 hour clock?

Hi
If you choose a 24 hour clock in UWC, all mail and calendar events looks correct. But all tasks still use 12 hour clock with AM/PM. Is this a bug? We have all products from JES2005Q1 + the xx540-10 uwc patch.
Is it a known bug or shall be logg a case?
Thanks
Per-Olov

Not a bug I know about, but I'm not very up on Calendar.
You may have to pick 24-hour clock separately in Calendar, as an option, there, too.

IOS 7.02 iPhone 5 clock and Calendar Problems

The date displayed in the Calendar is always one day ahead of its day shown in the iPhone settings date. Also the clock for the various cities around the World are being incorrectly reflected. Seoul, Korea is shown 2.5 hours earlier than Shanghai time and Seoul is East of Shanghai and I believe it is only 1 hour ahead not 2.5 earlier as shown in iPhone. Never had these problems before update to iOS 7.02. The World Clock and calendar cannot be trusted any more and I hope Apple will correct soon!!!!

Hello there, Duke4u.
The following Knowledge Base article provides some great troubleshooting steps for your issue:

If you've already reviewed the settings for Date & Time, what seems pertinent to you is the following:
If the incorrect date, time, or time zone is being set up automatically on the device, please notify your cellular provider. In the meantime, tap General > Date & Time and turn off Set Automatically. Then set the appropriate time and time zone manually.

How to select 12-hour clock in iPhone?

I'm using my iPhone 3G in the UK and would prefer to use the 12-hour rather than 24-hour clock format. Unfortunately the "24-Hour Time" on/off slider in Settings is grayed out and stuck on 24-hour format. How can I make this selection active so I can turn off the 24-hour format?

Basically your stuffed. If you want a 12 hour clock you need to use the USA settings, the problem then is that the date format is up the spout and the calendar in month view starts with a Sunday! Come on Apple give us in the UK the 12 hour option!

Iphone Time -24 Hour Clock

I use 24 the hour time setting vs. the 12 hour clock. Every so often the time reverts to the 12 hour clock. I have to go into "settings" and choose the 24 setting again. This happens once a week or so.
I have the latest iphone OS update. Anyone else have this problem?

I figured out that the problem occurs *every time a calendar event reminder on the iPhone pops up*: Both iPhone (FW 1.1.1) and MacBook (running Leopard 10.5) are set to 24h display, but when a calendar event on the iPhone pops up, the clock switches to AM/PM 12h display and needs to be switched back to 24h display via iPhone’s General Settings. Very annoying.

Hi Tech,
Base on my knowledge, the time formats of this message will follow the system time format.
If your system time format is 12 hours clock, the message will be the same.
In addition, 12 hours clock will include "AM" & "PM" words, however there are no these words in your message.
I recommend you check your system time format again, the following screenshot for your reference:

PC Suite : "2 hours" error in Calendar vs. handset...

Hi everyone
Everything on my laptop (PC Suite) Calendar is 2 hours earlier than on my handset's Calendar!
For example:
a) If I enter an appointment (using PC Suite's "Calendar" function) to start at, for example, 4pm... and then SYNCH with my mobile (a Nokia 6086), on the handset's Calendar the appointment will start 2 hours earlier - at 2pm!!
b) Similarly, If I enter an appointment (on the mobile) to start at, for example, 4pm... and then SYNCH, on my laptop (in PC Suite's "Calendar") the appointment will start 2 hours later - at 6pm!!
Can anyone help me? Thank you in advance for your ideas!
...Paul
Solved!
Go to Solution.

I also have this problem.
I always suspect a two hour error in calendar software to be a result of a bad module used to convert 24 hour time (military time) to 12 hour AM and PM (and vias versa). My phone and PC are set to display military time. Is this true of your use?
If so, it would explain the apparent rarity of this error being reoported.
I have the same model.

Obvious power issue effecting all back plane jks. Popping HOURLY (clocked) thru speakers, lites up lamp on doc scanner. Has blown power supply once. "Genius" diag NTF twice B4 power supply blew. Still have same trouble. I made very CLEAR to Genius Bar that it was a hardware issue after they continued to trouble shoot software. I was referred to tier 2 who told me they only worked on SOFTWARE. Does anyone know a more qualified shop who can fix an OBVIOUS mother board issue tracing back to the power supply? I had the same issue with a 20" with 7 visits & had to literally take a video of the trouble before they could figure out the trouble was the video card. From reading the sheer number of posts of the same trouble descriptions going back to 2007, it's all too obvious the path to MSFT is being taken.

Can Web Intelligence display time in 24-hour clock format?

I would appreciate your kind help in answering this question: How can I change the time format in a formula so as to display time in the 24-hour clock format?
          Presently the CurrentTime() value format looks like this : 02:26:25 PM GMT-04:00
          Instead, I want it displayed in the 24-hour clock format like this : 14:26
I'm developing Web Intelligence reports in the BusinessObjects Enterprise XI 3.2 InfoView environment.
I searched several places for an answer to this question, but had no luck.
I searched the BusinessObjects Enterprise InfoView online help document (i.e., Web Intelligence Java Report Panel); I also searched two web sites: the Experts-Exchange website, and the BOB www.forumtopics.com website.
I figured out that there is built in conversion function FormatDate() that can convert a date value into a text value, as for example : FormatDate( CurrentDate(); "mmmm dd, yyyy" )
However, I have not found an equivalent time function that would convert a time value into a text value of a specified format.

Anil,
     Perfect; you answered my question!
     The only thing that I had to do differently was to leave off the quote marks from the string "HH:mm:ss" when I entered it into the Custom Date/Time box of the Number Format dialog window.
     While on this subject of the Number Format dialog window, I saw that the Date/Time box already held the following string value:
                FULL_DATE
     So, thinking that I should leave that value alone, I entered the string "HH:mm:ss" in the box labeled "Undefined" next to the Date/Time box, instead. That didn't work. It just caused the webi report to display the CurrentTime() value as a long date, like this:
               Friday, July 9, 2010
     So then I replaced the string "FULL_DATE" (without the quotes) with the string "HH:mm:ss" (first with and then without the quotes). In the first try, the report displayed the time as "14:20:34"; in the second try, the report displayed the time as 14:20:34.
     Questions:
     Can you please tell me:
     1. What is the meaning and usage of the label FULL_DATE?
     2. In my attempts to get the time formatted the way I wanted it to look, I filled the Properties list (of the Number Format dialog window) with junk labels such as those listed below. How can I delete these labels?
               FULL_DATE; "HH:mm:ss"
               FULL_DATE
               FULL_DATE
               FULL_DATE; "HH:mm:ss"
     3. What is the purpose of the box labeled "Undefined" next to the Date/Time box?

Leading zeros with 24-hour clock?

I have my system preferences set to 24-hour clock.
How do I get the times to display with leading zeros?
For example, 06:45 instead of 6:45?

As I said before, you need to explore. I was able to add it in less than 30 seconds.
Let me try to explain. It is easy to do, but more difficult to explain.
Go to Sys Prefs/Int'l/Formats pane. Choose Custom in the Times area. Choose Medium in the Show drop down menu. (Medium seems to be the one used by OS X for the menu bar clock.) Here you can arrange the order of the different components as you like. Notice they have little arrows indicating drop down menus. Most of the optional formats offer a leading zero.
Even though you have formatted it in the Int'l pane, you must choose for some of your formating to show in the Date & Time/Clock pane.
Good Luck.

Hour clocks?

II'm looking to have a pie chart where I can show a one hour clock
i am helping out at a radio station and need to have an accurate template of when presenters play songs, talk, play ads and so forth. Is this possible in Numbers?
sorry if it's a dumb question. The iOS 8 version which I just got on my iPhone 6 plus has me amazed! Just hoping some one can give some simple
instructions for this novice!

Select both columns and insert a pie chart.
Select all segments (shift click) and set no fill.
Set Stroke to line
Labels choose data point names, not values
Adjust distance from centre to put labels outside the circle.
Copy the whole pie and paste. On the duplicate, remove wedge borders, hide labels, rotate 15 degrees.
Overlay the two pies.
I hope this screen shot shows.
Regards,
Ian.
