Hi Folks;

Here is my original post and the solution from Michael Sullivan:

Your TZ environment variable should be set to GMT+5. Solaris 2 follows
the POSIX standard interpretation of TZ, which says the numeric value represents
hours behind GMT. If your time appears to be correct with TZ set to GMT-5, your
system clock is set wrong.

Mail headers use the opposite convention, so your correct timezone for a mail
header is GMT-0500.

P.S. Solaris 1 had a bug which reversed the meaning of the number in the GMT+/-n
TZ values; this had the misleading side-effect of making the sign in the TZ
variable match that in mail headers, which seemed nice, but was wrong.
Solaris 2 has fixed the bug, and follows the POSIX standard.
