I want to display time formatted and converted to my users’ local time zones.
fb:time tag. The simplest form is:
<fb:time t="212698800" />
If that doesn’t look like a date and time to you, read on to the Discussion.
The tricky part here is that you have to pass in
t in what’s known as “epoch
seconds,” or the number of seconds that have elapsed since the Unix
Epoch, which was January 1, 1970. You think I’m making this up? You
couldn’t make this stuff up! No one would believe you. (See http://en.wikipedia.org/wiki/Unix_epoch for more
information on why we use this seemingly bizarre method of encoding a
date and time.) You might find yourself wondering how you’re going to
calculate that without doing a whole bunch of counting and skipping
leap years and remembering that 30 days hath September, April, June,
and November. Easy! To display the current time, just take advantage
of the PHP
time() function (or
an equivalent in your language of choice):
<fb:time t="<?php echo time();?>" />
To display a different time, use the PHP
mktime() function, which generates the
epoch seconds for any given date:
<fb:time t="<?php echo mktime(17, 35, 0, 4, 26, 2008);?>" />
The parameters, in order, are hours, minutes, seconds, month, day, and year. More info is at http://www.php.net/manual/en/function.mktime.php.
fb:time makes the
time display relative, so if
t is on the same day as today, you’ll just get the time (e.g., 5:35 p.m.); if it’s in ...
