Where can I find a routine for building an RFC 3339 time?
This was based on the examples on page 10 of the RFC. The only difference is that I am showing a microseconds value of six digits, conformant to Google Drive's timestamps.
from math import floor
def build_rfc3339_phrase(datetime_obj):
datetime_phrase = datetime_obj.strftime('%Y-%m-%dT%H:%M:%S')
us = datetime_obj.strftime('%f')
seconds = datetime_obj.utcoffset().total_seconds()
if seconds is None:
datetime_phrase += 'Z'
else:
# Append: decimal, 6-digit uS, -/+, hours, minutes
datetime_phrase += ('.%.6s%s%02d:%02d' % (
us,
('-' if seconds < 0 else '+'),
abs(int(floor(seconds / 3600))),
abs(seconds % 3600)
))
return datetime_phrase
