If the explicit time form of the sleep command (sleep hh:mm) is used in a loop (for example, forfiles), iterations following the first sleep command are likely to be in the past (perhaps by 1 second), causing some iterations to sleep until the next day.

For example, consider the following loop:

<pre>
forfiles src=*.txt sortby=createdate
    # Do some stuff
    ...
    sleep 5:00
end
</pre>

If the some stuff portion of each iteration of the loop took at least 1 second, the script would sleep for approximately 23 hours, 59 minutes, and 59 seconds, with each iteration following the first.
