How to get current time in Pacific Timezone when import pytz fails?

问题

I'm working in an environment (AWS Lambda) where import pytz doesn't work.

The environment is set to UTC.

How can I get the current time in the U.S. Pacific Timezone in this environment?

I need something simple, and low-maintenance. Somehow forcing import pytz to work would be ideal, and I hope to avoid having to copy the entire pytz library into my own script.

What have I tried so far? I tried using import pytz, and it failed with module not found.

Example code? I tried this, straight from another question on SO:

import pytz

eastern = pytz.timezone('US/Eastern')
utc = pytz.utc
test = '2013-03-27 23:05'

If you don't have access to pytz in your environment, maybe you have access to python-dateutil. In that case you can do:

import datetime
import dateutil.tz

eastern = dateutil.tz.gettz('US/Eastern')
datetime.datetime.now(tz=eastern)
