The uClibc time functions get timezone information from the TZ environment variable, as described in the Single Unix Specification Version 3. See http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap08.html for details on valid settings of TZ. For some additional examples, read http://www.uclibc.org/lists/uclibc/2002-August/004010.html in the uClibc mailing list archive. You can store the value of TZ in the file ‘/etc/TZ’ and uClibc will then automagically use the specified setting.
