[tz] No time zone on Solaris servers

[W CUI]

 "truss" command output is here. The date command is looking for the correct zoneinfo file, but there is no correct time zone output.

The date command output should be something like:Thu Aug 25 08:59:57 EDT 2022

Anyway, updating these two lines in Makefile then compile again seems fixed the problem. DATAFORM=               rearguardZFLAGS=         -b fat
Again, it is a very old Solaris 10 server. Thank you for your help.

Oh, sorry, I gave you the wrong shell command. It should be:

LC_ALL=C TZ=America/Los_Angeles truss date
