I want the menubar to display the date and time in the menubar as follows:

2012-10-03 09.12.14

which translates into Year-Month-Day 24hr.min.second

What I've tried:

Gone into System Preferences > Date & Time > Clock

Selected: Digital; Display time with seconds; use 24-hour clock

This gets me close to having the time right.

Gone into System Preferences > Date & Time > Date & Time > Open Language & Text > Formats > Dates > Customize

Changed every date format (short, medium, long, full) to have yyyy-MM-dd

Gone into System Preferences > Date & Time > Date & Time > Open Language & Text > Formats > Times > Customize

Change every time format to

The problem:

It still shows the date like:

3 Oct 13:19:12

in the menubar.


I am running Mac OS X 10.7.5

Any help or suggestions you can give, much appreciated!

Whilst I'm not sure this is possible with the built-in menubar clock formats, you can acheive the format you require using the excellent iStat Menus ($16, but it does have a 14-day free trial).

Are you aware that OS X uses multiple Formats for Date and Time (depending on where it is shown) and you must modify the right one? E.G. the timestamp in Finder has a different format than in the top right corner.

Any idea which one? I've tried several combinations like the OP has and it only modifies the way the date/time is shown in the Finder, not the date/time displayed in the menubar – binarybob Oct 3 '12 at 8:04
I've modified all of them to be identical to what I want. The problem remains. – JBWhitmore Oct 3 '12 at 11:41
mhm I even found this… maybe it is a bug – miceterminator Oct 3 '12 at 12:43
