'''ctime''' in a [[Unix]] [[filesystem]] is a [[file]] attribute which tells when the file's directory entry (inode) was last modified. See: [[Stat (Unix)]].

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
