Fix for time_proc, methods like date_time should return time in UTC

[mshytikov]

According to http://www.exif.org/Exif2-2.PDF
UTC is not obligatory from the spec but this should help to avoid problem with time zones .

I don't agree, it will introduce more time zone problems because more
than 90% of the camera's have their clock set to local time and users of
this module will most likely have their computer setup in the same
zone. Converting the timestamps of their photo's to UTC will introduce
the extra zone offset.

But I do agree it's a nuisance. Ruby doesn't make it very easy to
handle time zones well. ActiveSupport together with TZInfo do a nice
job but I can't find a way to take advantage of that without depending
on them.

A proper solution is to allow passing in tz information for mktime
either via a thread local or an options map at JPEG and TIFF
initialization and falling back to the current behaviour. That's a pull
request I will consider.
