The react shift form calculates the start time to the nearest half hour
to "now". It then sets the end time to 2 hours after that. If this test
is run between 10pm and 12am local time (or if local time converted to
UTC is in that range) the end time will be earlier than the start time.
This causes the test to fail.
The fix is to set the times manually. The value to set the time fields
is a bit odd: 03:00AM but it's sending those keys directly to the
field. If you were typing it by hand, you wouldn't add a space and so
we don't do that here for the same reason.
