SUMMARY: Timezone for Puerto Rico

Date: Mon Apr 17 1995 - 12:46:26 CDT

     Original inquiry:
        I'm at a loss here. After scouring /usr/share/lib/zoneinfo, I
        can't seem to find an appropriate timezone for Puerto Rico. They
        do not observe Daylight Savings Time, and their standard time is
        one hour ahead of EST (GST-4). I think the timezone is actually
        called Atlantic Standard Time, but there's no equivalent in the
        zoneinfo directory. This is probably pretty simple, sorry to bring
        such a trivial request to the list. (Although my customers in PR
        certainly didn't like the sudden change in their clocks last week.)
     First, I forgot to mention I am using SunOS 4.1.3. There's no
     reference to Puerto Rico, although it seems there is in later OS
     versions (or zoneinfo versions..)
     There are ftp sites that have up-to-date versions of the zoneinfo
     database, although they may need recompiling (using 'zic'). One such
     site is "". (Although this doesn't help me at the
     moment, I don't have full Internet access :( )
     I went with GMT-4. It doesn't look very nice in the "date" command,
     but it will provide the correct timezone year-round. I suppose I
     could link GMT-4 to "Atlantic" or "AST" or something...
