Converting ArcGIS Online UNIX time to a standard readable date/time format

AGO_UNIXTimeConv.py

# Modify time formatting codes (e.g., "%Y", etc.) as needed using values from table in python docs here:
# http://docs.python.org/2/library/time.html#time.strftime

# Replace <AGO DATE/TIME> with your time value/variable

import time
time.strftime("%Y-%m-%d %I:%M:%S %p (%Z)",time.localtime(<AGO DATE/TIME>/1000))

# SAMPLE RESULT - '2013-07-31 11:59:33 PM (Eastern Daylight Time)'

##########

# alternate usage -- selects your locale's appropriate date/time representation
import time
time.strftime("%c (%Z)",time.localtime(<AGO DATE/TIME>/1000))

# SAMPLE RESULT - '07/31/13 23:59:33 (Eastern Daylight Time)'
