test-webkitpy fails on metered_stream_unittest for non-US West Coast Time Zones
https://bugs.webkit.org/show_bug.cgi?id=83583

Reviewed by Philippe Normand

Updated the unit test to ignore the hours and minutes of the
localtime for time(0), since we can't easily guarantee which
timezone we're in or what timezone rules were in effect on
1/1/1970; this should be mostly fine since we can trust that
time.localtime() will work, although there is the possibility
that we'll screw up the time formatting of which field is the
hours and which is the minutes.
