Hi, just passing along an update to the system tzdata patch that we're 
using in Fedora, the latest version is v10 here courtesy of Remi:

Add support for use of the system timezone database, rather
than embedding a copy.  Discussed upstream but was not desired.

History:
r10 : make timezone case insensitive
r9: fix another compile error without --with-system-tzdata configured (Michael Heimpold)
r8: fix compile error without --with-system-tzdata configured
r7: improve check for valid timezone id to exclude directories
r6: fix fd leak in r5, fix country code/BC flag use in 
    timezone_identifiers_list() using system db,
    fix use of PECL timezonedb to override system db,
r5: reverts addition of "System/Localtime" fake tzname.
    updated for 5.3.0, parses zone.tab to pick up mapping between
    timezone name, country code and long/lat coords
r4: added "System/Localtime" tzname which uses /etc/localtime
r3: fix a crash if /usr/share/zoneinfo doesn't exist (Raphael Geissert)
r2: add filesystem trawl to set up name alias index
r1: initial revision
