Getting the RFC 3339 timestamp for a day ago

Looking at this answer I can get the RFC 3339 based time fairly easily as the code for it shows:

d = datetime.datetime.utcnow() # <-- get time in UTC
print d.isoformat("T") + "Z"

I am wondering how I would get the same format of time, but for exactly one day ago. It would essentially be day-1, however I am not sure how to do this.

You can get one day previous to x with:

x = x + datetime.timedelta(days = -1)

The following transcript shows this in action:

>>> import datetime
>>> d = datetime.datetime.utcnow()
>>> d
datetime.datetime(2014, 2, 26, 1, 11, 1, 536396)

>>> print d.isoformat("T") + "Z"
2014-02-26T01:11:01.536396Z

>>> d = d + datetime.timedelta(days=-1)
>>> d
datetime.datetime(2014, 2, 25, 1, 11, 1, 536396)

>>> print d.isoformat("T") + "Z"
