Python snippet to get the PST time and date.

PST.py

from datetime import datetime
from pytz import timezone

def get_pst_time():
    date_format='%m_%d_%Y_%H_%M_%S_%Z'
    date = datetime.now(tz=pytz.utc)
    date = date.astimezone(timezone('US/Pacific'))
    pstDateTime=date.strftime(date_format)
    return pstDateTime

Pacific time is different from PST. It switches to PST or PDT according to date.
