Need to figure out start time

[SharkBait]

Trying to figure out the mktime of 6:45am of this day.

I'm doing: mktime(6,45);

Is that right?

What I will be doing is using that as my start time, then finding out what my current time is and substracting the two to see how much time has passed since.

Looks good, you can double check here if you want a reference:

wouldn't it be easier to just do like

[code]
$start = time();

//do code stuff here or whatever

$end = time();

$lengthoftime = $end - $start;
[/code]

It would but I need it to set the start time at 6:45am everyday.

So this is what I ended up with:
[code]
<?php

$TotalUnits = 0;
$sStart = mktime(06,45,0);
$sCurrent = mktime();

$betweenTime = substr(($sCurrent - $sStart) / 3600, 0, 3);

$startTime = date("Y-m-d 06:45:00");
$currentTime = date("Y-m-d h:m:s");

foreach($UNITS as $table => $name) {
  $strqry = "SELECT COUNT(*) as count FROM {$table} WHERE Real_Date = '{$startTime}' AND Real_Date <= '{$currentTime}'";
  $query = mysql_query($strqry) or die("MySQL Error: <br />{$strqry} <br /> ". mysql_error());
  $result = mysql_fetch_array($query, MYSQL_ASSOC);
  $TotalUnits = $TotalUnits + $result['count'];
}
echo substr($TotalUnits / $betweenTime, 0,2);
?>
[/code]
So now I can check between 6:45am and the current time, count the units that were entered and find the units per hour value :)
