I was looking for something like shown on the map:

Information about local daylight savings times would also help.
The data are from ships, supposedly in local time, but no time-zone info is
given. A function that would return time zone and whether or not daylight
savings time applies at given date would would help. I'm trying to track
down more information about the data and whether they can be referenced to
UTC.
The zone.tab file has this information. See the Examples section at
the end of ?Sys.timezone for info on its whereabouts.
On some OSes only.
