Support TZ transition times < 00:00:00.
This is needed for version-3 tz-format files; it supports time
stamps past 2037 for America/Godthab (the only entry in the tz
database for which this change is relevant).
* manual/time.texi (TZ Variable): Document transition times
from -167:59:59 through -00:00:01.
* time/tzset.c (tz_rule): Time of day is now signed.
(__tzset_parse_tz): Parse negative time of day.

 * On Linux, the clock function now uses the clock_gettime system call
   for improved precision, rather than old times system call.
 
+* Added support for version-3 tz format files.  This is needed when using
+  the tz database release 2013e or later, and affects a few unusual cases --
+  currently only TZ='America/Godthab' for time stamps after 2037.
+
 * Added new API functions pthread_getattr_default_np and
   pthread_setattr_default_np to get and set the default pthread
   attributes of a process.
