in computer programming languages CTime or ctime may refer to:

ctime(), a function in the ISO C standard library defined in the time.h standard header
<ctime> is a standard header file for C++, equivalent to the C standard library header, <time.h>
st_ctime, a member of the stat structure specifying the last inode change time of a file in a Unix-like filesystem
CTime, a Microsoft ATL/MFC class for handling dates and times
CTime, a datatype in the Haskell programming language corresponding to the C time_t type
Time::CTime, a Perl module for interfacing with POSIX asctime

-In [[computing]], '''ctime''' is the number of seconds since 0:00:00 [[January 1]], [[1970]] [[UTC]]. Commonly stored as a 32 bit signed [[integer (computer science)|integer]], this number is used for pinpointing dates in many [[computer]]s and [[operating system]]s, such as [[Linux]] and [[Unix|UNIX]] variants, as well as some [[programming language]]s. For example, the function ctime() was included in [[ANSI C]]. It will [[arithmetic overflow|overflow]] in [[2038]] and cause the [[year 2038 problem]]; some expect this will be a profitable non-event similar to [[Y2K]].

+{{disambiguation}}
-To determine the current '''ctime''' on a UNIX system, issue the command "<code>date +%s</code>".
-'''ctime''' is also a [[Unix]] library call which returns the local time as a human readable [[ASCII]] string.
-'''ctime''' in a [[Unix]] [[filesystem]] is a [[file]] attribute which tells when the file's [[inode]] was last modified. See: [[Stat (Unix)]].
