#11431: Possible time-zone problem with computing uptimes and downtimes

 Could it be that Globe interprets `last_seen` and `last_restarted` as
 datetimes in the user's local timezone?

 I looked up a random non-running relay and found the following line in its
 Onionoo details file:

 {{{
 "last_seen":"2014-04-07 08:00:00",
 }}}

 It was 18:26:00 CEST when I looked up the relay in Globe, so 16:26:00 UTC.
 Globe told me the downtime was 10 hours 26 minutes.  But it should have
 said 8 hours 26 minutes.

 Similarly, I looked up another random relay, but this time one that was
 running.  It's Onionoo details file contained this line:

 {{{
 "last_restarted":"2014-04-07 09:18:05"
 }}}

 I looked it up in Globe at 18:31:00 CEST, so 16:31:00 UTC, and Globe told
 me the uptime is 9 hours 13 minutes.  It should have said 7 hours 13
 minutes.
