Time zones and Star-Net

System setup: HP-UX A.09.01 on HP 9000/755 Informix Online, Star, ESQL, all ver 5.03.UC1 Informix-SQL ver 4.12.UE1 I have SQL which calls a stored procedure to query realtime weather data, for later input into an ACE report. The data are queried based on their observation times, which were encoded by the observers in the data reports before they were transmitted long-line. External programs decode these reports upon reception for insertion into the Informix database. The observation date/times are all in UTC time (6 hours later than CST/5 hours later than CDT). All our external programs expect UTC observation times. What I query depends on what the system UTC time is. What I get when I query system time in the SPL is Central Time. This was easy to fix, by "export TZ=UTC0UTC". However...this only seems to work when the SQL is run on the server containing the database. For instance, when doing: dbaccess rfcdb getdata.sql on the server, with the TZ variable redefined to UTC, the SPL uses UTC time. But, if I do: dbaccess rfcdb@wi getdata.sql from a client, or even on the "wi" server, the SPL uses the local (Central) time, ignoring the exported TZ variable. Is there anyway to pass the TZ info to the server when using the network? The above SQL is mostly a black-box process that runs on cron, with users just looking at the finished results. But if someone corrects bad data and wants to manually rerun the shell script, they have to rlogin to the server and run it from there, which is kind of a pain. I suppose I could work around this with a lot of programming, but seems like I shouldn't have to.
