When providing an offset, leave off the trailing "Z".
On a Linux host, run:

to see an example for your currently configured place and time.
As others have said, I think you would do better to delegate this conversion to a timezone database, as accessed through your API of choice, and send only UTC times over the wire.
fyi. On Linux, it is easy enough to override timezone on a per-process basis with the $TZ environment variable.

cf. /usr/share/zoneinfo/ and "man tzset"
