zdump and zic no longer warn about valid time zone abbreviations
like '-05'.
Some Visual Studio 2013 warnings have been suppressed.
(Thanks to Kees Dekker.)
'date' no longer sets the time of day and its -a, -d, -n and -t
options have been removed. Long obsolescent, the implementation
of these features had porting problems. Builders no longer need
to configure HAVE_ADJTIME, HAVE_SETTIMEOFDAY, or HAVE_UTMPX_H.
(Thanks to Kees Dekker for pointing out the problem.)
Changes affecting documentation
The Theory file mentions naming issues earlier, as these seem to be
poorly publicized (thanks to Gilmore Davidson for reporting the problem).
tz-link.htm mentions Time Zone Database Parser (thanks to Howard Hinnant).
Mention that Herbert Samuel introduced the term "Summer Time".
