Top Forums UNIX for Advanced & Expert Users Add file creation date as new column Post 302849089 by Don Cragun on Friday 30th of August 2013 10:17:52 PM

Although some filesystems do have a file creation timestamp, most do not. The standards only require three timestamps for files (last access timestamp, last data modification timestamp, and last status change timestamp). Many people incorrectly refer to the last status change timestamp as the file creation timestamp, but it is marked for update to the current time not only when a file is first created but also whenever the size of the file changes, the mode of the file changes, or the ownership of the file changes.

By default ls -l displays the last data modification timestamp, ls -lu displays the last access timestamp, and ls -lc displays the last status change timestamp.

gmstrftime - Format a GMT/UTC time/date according to locale settings

SYNOPSIS
string gmstrftime (string $format, [int $timestamp = time()]) DESCRIPTION
Behaves the same as strftime(3) except that the time returned is Greenwich Mean Time (GMT). For example, when run in Eastern Standard Time (GMT -0500), the first line below prints "Dec 31 1998 20:00:00", while the second prints "Jan 01 1999 01:00:00". PARAMETERS
o $format - See description in strftime(3). o $timestamp - The optional $timestamp parameter is an integer Unix timestamp that defaults to the current local time if a $timestamp is not given. In other words, it defaults to the value of time(3). RETURN VALUES
Returns a string formatted according to the given format string using the given $timestamp or the current local time if no timestamp is given. Month and weekday names and other language dependent strings respect the current locale set with setlocale(3). EXAMPLES
Example #1 gmstrftime(3) example <?php setlocale(LC_TIME, 'en_US'); echo strftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . " "; echo gmstrftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . " "; ?> SEE ALSO
strftime(3). PHP Documentation Group GMSTRFTIME(3)
All times are GMT -4. The time now is 02:43 AM.
