c
ctime(3C) ctime(3C)
WARNINGS
Users of asctime_r() , ctime_r(), gmtime_r() , and
localtime_r() should also note that
these functions now conform to POSIX.1c. The old prototypes of these functions are supported for compati-
bility with existing DCE applications only.
The range of
tm_sec([0,61])
extends to 61 to allow for the occasional one or two leap seconds. How-
ever, the ‘‘seconds since the Epoch’’ value returned by time(2) and passed as the timer argument does not
include accumulated leap seconds. The
tm structure generated by
localtime() and gmtime() will
never reflect any leap seconds. Upon successful completion,
mktime() forces the value of the tm_sec
component to the range [0,59].
AUTHOR
ctime() was developed by AT&T and HP.
