Agree that it should go into a date and time SRFI.

-1.  I want date/time to be fully portable, no dependencies on the current anything except the current TAI-UTC table, which is unavoidable.  See TimeAdvancedCowan.  See also my previous post for the issue with TZ.

That's a very good point.  Which means we should add back a current-timezone, properly specified as an input to the new SRFI, with how you determine it also specified, read-link magic and/or groking the format ... and don't you have to grok the formats of the two types of files to digest them?
