Generating "TZ" string from /etc/localtime?
by Philip A. Prindeville March 29, 2009

March 29, 2009

Sorry if this is answered somewhere and I just haven't come across it. I'm the lead developer for Astlinux: http://www.astlinux.org and we're using uClibc in an embedded Linux environment. We need a way of parsing out zoneinfo files (starting with whatever /etc/localtime links to) and dumping out the string at the end: I was looking in tzcode2009.tar.gz and couldn't find a function to parse a tzfile... sort of the complement of writezone() in zic.c. Also, are there any patches to make cross-compilation or packaging (a la DESTDIR) easier? Thanks, -Philip

The files... ftp://elsie.nci.nih.gov/pub/tzcode2009d.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2009d.tar.gz ...are now available; these reflect the Morocco, Tunisia, Argentina, and American Astronomical Society changes circulated last week on the time zone mailing list. There may well be an update for Pakistan shortly; folks who want to avoid thrashing may want to wait for tzdata2009e.tar.gz. --ado
