Thanks; I've used your solution almost identically except I decided I
wanted the opposite sign:
do
local now = os.time()
localtime_minus_UTC = os.difftime(os.time(os.date("*t", now)),
os.time(os.date("!*t", now)))
end
I've tested this on a number of email messages (my application) and
the results look good.
Thanks!
