Timers in Program (Elapsed time) doubt

Could you tell me something about the Program's time element?

If I set 1 day of elapsed time to send a campaign, is this time counted as 24 hours?

Example: The program launches a campaign today at 09:00 am, after a 1 day delay (elapsed time). The next campaign will be launched the next day at 09:00 am?

Here is a representation of my doubt:

Is this thought correct?

Thanks
