Add LOGGER_TIMEZONE env to control the time zone

Browse source 
Closes #23

If the name is "" or "UTC", LoadLocation returns UTC. If the name is
"Local", LoadLocation returns Local.

Otherwise, the name is taken to be a location name corresponding to a
file in the IANA Time Zone database, such as "America/New_York".

LoadLocation looks for the IANA Time Zone database in the following
locations in order:

the directory or uncompressed zip file named by the ZONEINFO environment
variable
on a Unix system, the system standard installation location
$GOROOT/lib/time/zoneinfo.zip
the time/tzdata package, if it was imported
