I am having a date time comparison issue.
I have statically set the values here. But the data is fed from the database, CaldTime is timestamp and since it will not allow me to have 2 timestamps in the same table I set the CallEnd varchar(12). Storing the data they seem to be the same for output. I checked hexadecimal and binary to look for obscurities.


$sqldata['CaldTime'] = "2008-04-07 11:15:32";
$sqldata['CallEnd'] = "2008-04-07 11:17:17";

$time1 = strtotime("$sqldata[CaldTime]");
$time2 = strtotime("$sqldata[CallEnd]");
$interval = $time2 - $time1;

echo $interval;

++++++++++++++++++++++++++++++++++++++++++++++++++ +++++
Displays like 1.75:0
I am looking for a more precise time like 1:45 instead.
Am I looking at this all wrong for time difference?

hmm.
different results for me w/ this code

<?php
$time1 = strtotime('2008-04-07 11:15:32');
$time2 = strtotime('2008-04-07 11:17:17');

echo "time1: $time1" . PHP_EOL;
echo "time2: $time2" . PHP_EOL;

$interval = $time2 - $time1;
echo $interval . PHP_EOL;
?>

time1: 1207588532
time2: 1207588637
105

?? What database are you using? It sounds like it has a specific
meaning of "timestamp" - probably "the last time this row was
modified" - and you want an arbitrary date column, which would
probably be a different column type. Not a string, though. An actual
date type. possible names are date, datetime, datestamp...


, and you I set the CallEnd varchar(12). Storing the data they seem
to be the same for output. I checked hexadecimal and binary to look
for obscurities.

strtotime returns an integer number of seconds. The difference
between $time1 and $time2 is 105. If you want minutes and seconds,
you have to do the math yourself.

$interval_min = floor($interval/60);
$interval_sec = $interval % 60;

echo "$interval_min:$interval_sec";

This could be simplified to a function, but using some basic math....

<?php
$sqldata['CaldTime'] = "2008-04-07 11:15:32";
$sqldata['CallEnd'] = "2008-04-07 11:17:17";

$converted = explode('.',((strtotime($sqldata['CallEnd']) -
strtotime($sqldata['CaldTime'])) / 60));
$converted[1] = (($converted[1] / 6) * 3.6);
echo implode(':',$converted)."\n";

?>
