Date and Time

To display current date/time, use:

echo date('F d, Y H:i:s');

The result will be something like:

August 08, 2008, 14:06:39

To display a certain date or time formatted in a certain way, use mktime() and date(). It takes two arguments: the format that describes how to print the date and the time stamp that represents the date you want to print.

<?php
$dataEntry = mktime(18,15,0,1,10,2001);
$x = date('F d, Y - g:i a',$dataEntry);

echo "$x"
?>

will produce:

January 10, 2001--6:15 p.m.

To deal with times in Greenwich Mean Time (GMT), you can use gmdate() and gmmktime(). For example, for a machine in eastern daylight time, which is four hours behind GMT:

<?php
$today = mktime(12,0,0,6,6,2001);
echo 'Here it is '.date('g:i:s a, F d, Y',$today);
echo '';
echo 'In GMT it is '.gmdate('g:i:s a, F d, Y',$today);
?>

will produce:

Here it is 12:00:00 pm, June 6, 2001
In GMT it is 4:00:00 pm, June 6, 2001
