Setting timezone manually

[Magnus Schmidt]

Hello,

 I have a weewx-Installation which replicates the SQLite-database regularly to an server in another timezone. On the target-server wee_reports is run to update the web pages. As the target-server is in another timezone, the report contains the wrong time offset (I want to the times reported of the original station).

How can I set the timezone manually?

I did not find a config option. I tried to run "TZ='Europe/Lisbon'; wee_reports", but this does not work either.

Note: I cannot change the timezone on the server system wide.

Thanks,
Magnus

Unfortunately, changing the timezone system-wide is your only option. Weewx has no notion of timezones. It uses the system zone exclusively.

Making weewx timezone aware would introduce a couple of extra dependencies, plus weewx would have to deal with DST explicitly.

Maybe it depends on the OS… on my debian (wheezy) system, “TZ=US/Eastern; export TZ;  wee_reports” has the desired effect. Magnus, note that TZ needs to be an environment variable (exported or setenved, depending on what shell you’re using).  By default on my debian system, TZ isn’t set, so “TZ=US/Eastern; wee_reports” does NOT work — the “export” is needed.

Very clever, Les. Yes, that could work.

Hi Les,

 thanks, your suggestion worked! Timezone is now set correctly and output ist correct. The export statement is indeed mandatory.

Also thanks to Tom for this cool software.
