date in verbose port installed output: should it include time zone?

[Ryan Schmidt]

r146757 added date information to the output of `port -v installed`, e.g.:

$ port -v installed zlib
The following ports are currently installed:
  zlib @1.2.8_1+universal (active) platform='darwin 15' archs='i386 x86_64' date='2016-04-12 13:52:04'

I'm concerned that this is not displaying a time zone. Is the full time stamp, including time zone, stored in the database, and just being omitted for display purposes?

Would it be a good idea to add time zone information to the display? Would it be a good idea to use a standard date/time format, such as ISO 8601, in which case the output might hypothetically look like:


The following ports are currently installed:
  zlib @1.2.8_1+universal (active) platform='darwin 15' archs='i386 x86_64' date='2016-04-12T13:52:04-0500'
