A Windows clock to show both UTC and local time?

Solution 1:

One third party app that will allow you to do have both times always shown in the tray is StoicJoker's T-Clock2010: http://www.stoicjoker.com/tclock/

Edited on 2015-01-27: Thanks to JourneymanGeek for pointing out that StoicJoker's site is down. Most recent "incarnation" seems to be this (i did not test this personally, just searched around for 5 minutes): https://github.com/White-Tiger/T-Clock/releases/tag/v2.3.2%23151-beta (or to get latest version simply: https://github.com/White-Tiger/T-Clock/releases) (Find "T-Clock Help.rtf" within the release to get details on how to use time/date functions.)

Solution 2:

You can actually accomplish this using the system clock.

1. Click on the tray clock
2. At the bottom, click Change date and time settings
3. Click the Additional Clocks from the top menu bar
4. Tick Show this clock and modify the time zone to suite your needs.
5. Hit Apply

Solution 3:

Since your using Windows 7 the clock desktop gadget is one option. You can have multiple, name them and make them always on top. There are alternative versions that are more compact with similar settings.
