Strip timezone and microseconds in Python

usable_times.py

from datetime import datetime

# Prints a string that looks like: 2017-08-30T21:19:30 (this is a good standard ISO format)
current_time = datetime.utcnow().replace(tzinfo=None, microsecond=0).isoformat()
print(current_time)
# 2019-02-04T19:44:04

# To read in a string like above
date_obj = datetime.strptime(current_time, "%Y-%m-%dT%H:%M:%S")

#####
# Even better than above:
dt_str = datetime.utcnow().replace(tzinfo=None, microsecond=0).isoformat() + 'Z'
print(dt_str)
# 2018-10-23T21:00:24Z

# And to read the above:
date_obj = datetime.strptime(current_time, "%Y-%m-%dT%H:%M:%SZ")

## EPOCHs:
epoch = int(datetime.utcnow().timestamp())
print(epoch)
# 1549340128
