Thanks Mike;

I very much appreciate your comments and time!

I'd just finished making something similar work:

import pytz
# ...
time_local = 'America/Chicago'
time_fmt = "%Y-%m-%d %H:%M"
arrive_dt = datetime.utcnow()
testDt=pytz.utc.localize(arrive_dt)
TestDt = testDt.astimezone(pytz.timezone(time_local))
Arrive=TestDt.strftime(time_fmt)

I appreciate you,
Dale
