Only if somebody builds the database without the "backwards" file, which lists the backwards-compatibility names. The default is to include "backwards", as it includes very common IDs like US/Pacific. I'd be surprised (but not astonished) if someone omitted it.
FreeBSD does not use "backwards": ---------------------------- revision 1.6 date: 1994/09/13 21:54:06; author: wollman; state: Exp; lines: +36 -133 New method for installing timezone data files, not nearly as complicated as the previous one, and better integrated with the build scheme. Define OLDTIMEZONES to get backward-compatibility links added. Define LEAPSECONDS if you want leap-second support. ============================================================================= This change was made prior to the release of FreeBSD 2.0. FreeBSD 1.x (long obsolete) did support the old names. (I don't recall whether it supported the new names, but I suspect it didn't.) -GAWollman
