```{index} single: ctime; POSIX function ``` ```{index} single: POSIX::ctime; Perl function ``` # ctime Canonical English timestamp string for an epoch time, in local time. ## Synopsis ```perl use POSIX qw(ctime); print ctime(time); # "Wed Apr 22 14:30:00 2026\n" ``` ## What you get back A 25-byte string including the trailing newline, or `undef` on conversion failure. ## Differences from upstream Fully compatible with upstream POSIX. The trailing newline is preserved. ## See also - `asctime` — same formatting, but from a broken-down time list.
