Time converter so I can read timestamps

convert_epoch_time.py

#!/usr/bin/env python
from datetime import datetime as dt

import sys


def main():
  if len(sys.argv) < 3:
    print ('Converts epoch milis/micros to human-readable timestamps.\n'
           'Usage: ./convert_epoch_time.py micros <micros>\n'
           '       ./convert_epoch_time.py millis <millis>')
    return
  if sys.argv[1] == 'micros':
    print 'Calculating microseconds:'
    print dt.fromtimestamp(int(sys.argv[2])/1000)
  if sys.argv[1] == 'milis' or sys.argv[1] == 'millis':
    print 'Calculating milliseconds:'
    print dt.fromtimestamp(int(sys.argv[2])/1000000)


if __name__ == '__main__':
  main()
