Without a time zone set, AstLinux will display UTC.
Non-AstLinux Specific (uClibc)
To set a time zone use the /etc/TZ file. Copy & paste the time zones from the table below into the file. In this example it's done with the echo command.
echo "CET-1CEST-2,M3.5.0/02:00:00,M10.5.0/03:00:00" > /etc/TZ
NOTE: This sets the time zone for CET/CEST (Central European Time UTC+1 / Central European Summer Time UTC+2) and the start (5th week of March at 02:00) and end times (5th week of October at 03:00) of DST (Daylight Saving Time).

Please update and include your time zone. You can find more on time zones at T.A.M.A.O. and on timeanddate.com.
1in August of 2005, the United States President Bush passed the Energy Policy Act, which, among other things, changes the time change dates for daylight saving time from the first Sunday in April to the second Sunday in March and from the last Sunday in October to the first Sunday in November. This pattern starts in 2007, however, and Congress still has time to revert the DST back. As such, these changes have not yet been incorporated into mainline uClibc (which provides the time functions for the C library used by OpenWrt). Therefore, it might be a good idea to change /etc/TZ explicitly (around mid-November 2006) to reflect this change (i.e., instead of EST5EDT write EST5EDT,M3.2.0,M11.1.0).
