In this article, I would like to share how to set the timestamp on various email client such as Squirrelmail, Horde, Roundcube, Outlook2007 and thunderbird
SquirrelMail
Go to the Squirrel mail webmail program and click Options at the top.
Click the first link called Personal Information.
Under Timezone Options, look for “Your current timezone:” Change the drop-down to your time zone.
Click the Submit button.
Horde
Go to the Horde webmail program and click Options at the top.
Click the second link called Locale and Time. Look for “Your current time zone:”
Change the drop-down to your time zone.
Click the Save Options button.
RoundCube
Go to the Roundcube webmail program and click Personal Settings at the top right.
Under User Interface, look for “Time zone”
Change the drop-down to your time zone.
Click the Save button.
Outlook 2007
At any time, you can change the time zone in Outlook so that it matches your current geographic location. Please consult the Outlook Help menu for assistance with other versions
On the Tools menu, click Options. Click Calendar Options.
Click Time Zone.
Under the current time zone, type a name for the current time zone in the Label box. In the Time zone list, click the time zone that you want to use.
If you want your computer clock to automatically adjust for daylight saving time (DST) changes, select the Adjust for daylight saving time checkbox. This option is available only in time zones that use daylight saving time (DST).
Click OK and you are done.
Thunderbird
A Mozilla application has no clock of its own. It uses your system clock. Your system clock is controlled by your operating system settings.
