Windows – A Windows clock to show both UTC and local time

clocktaskbartime zoneutcwindows

I'm working on windows 7 x64 and searching for a way for a setting, or replacement app of, the tray clock (on the taskbar corner) to display both UTC (or GMT) and my local time.

Cause: I read log output of several programs realtime, many of them logging in UTC, while meetings (and other people synchronization stuff) is in localtime. Thus I would like to be able to see both local and UTC time in parallel on the system clock. I'm task-switching between many programs, so I'd like it to be always visible.

If I must use a replacement, I would like it to integrate into the taskbar/tray somehow, due not wanting it to cover any screen place that it not occupy fully.

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.)

Windows – Does Windows 7 support UTC as BIOS time

Have a look at this page:

Save the following lines as utc.reg, and then run it to import this registry tweak. It allows you to set the hardware clock in your PC’s BIOS to UTC time. This is handy for boot dual-booting Mac, or Linux, when those operating systems are set to read the BIOS clock as UTC time, instead of Windows’ preferred Local Time (e.g., PST, PDT, MST, MDT, CST, CDT, EST, EDT, or the standard “GMT-” and “GMT+”)

Here is the code to save as utc.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001

Linux – Set Windows to use system clock as UTC

Linux usually uses a tool called hwclock to interface with the hardware clock. Depending on your distribution, you should be able to modify the system startup scripts to make hwclock reread and store the time using current system timezone.

In Ubuntu, you can enable local time mode by editing /etc/default/rcS to:

UTC=no

I know, not exactly what you asked for, but it does make both OSes use the same clock offset.
