Tagging issue #908. It also looks like the code invokes utcnow in a few other places as well that could be worth updating.

howdy/src/compare.py
74:		_("Date: ") + datetime.datetime.utcnow().strftime("%Y/%m/%d %H:%M:%S UTC"),

howdy/src/snapshot.py
56:	filename = datetime.datetime.utcnow().strftime("%Y%m%dT%H%M%S.jpg")

howdy/src/cli/snap.py
44:	_("Date: ") + datetime.datetime.utcnow().strftime("%Y/%m/%d %H:%M:%S UTC"),
