Timezone GMT+2 and Date behavior

[avi_kosk]

Hi,   I set the same timezone GMT+2 in three different machines, running the following O/S:   Tru64 4.0D, Solaris 8, Linux RH 7.2   In order to get the time difference between the GMT+2 time and the UTC time, I just typed the "date" and "date -u" in all the three machines, and suprisingly, the UTC time in Linux and Solaris 8 is two hours MORE then the GMT+2 time. The Tru64 results with correct values (UTC time is two hours LESS then the GMT+2 time).   Tru64 results: #date Tue Oct 29 19:09:22 GMT+0200 2002 #date -u Tue Oct 29 17:09:27 UTC 2002   Linux results: #date Tue Oct 29 19:09:40 GMT+2 2002 #date -u Tue Oct 29 21:09:45 UTC 2002   What is the reason for such differences?. Are there different UTC standards for Linux and Tru64?   Any suggestion is appreciated.   Avi Koski
