Upload takes too long.

[Makada]

Hi all,

I have an upload script which uploads data every 5 minutes at every 00:00 00:05 00:10 00:15 and so on during 24/7.

But sometimes the upload takes too long.
The interval must be exactly at every 5 minutes and zero seconds,
Or for example when an upload is at 00:05:01 the next upload has to be at 00:10:01 with the same amount of seconds after the minute.
As you can see in the example upload below, one upload is done at 16:50:11 and the next upload is done at 16:55:01.
So thats shorter then exactly 5 minutes and zero seconds and thats why it gets an error and wont upload.
Ive also tried the "schedule.every(5).minutes.do(task)" but that wont start at exactly every 00:00:00 00:05:00 00:10:00 and has the same non exact interval.
My python script is included.
