The PVR backend (as the server side part), which directly communicates with a TV tuner adapter(s) to receive the Live TV signals and create a video or audio stream, and also record to files.
1. Convert time between hour, minute, second, or day with conversion factor. As we known, 1 hour = 60 minutes = 3600 seconds =1/24 day. So we can convert the time measurement with multiplying these factors. Convert between hours to seconds:
The simplest way to convert a time to a number of minutes is to multiply the time by 1440, which is equal to 24*60 (the number of minutes in one day): For the time 02:30:30, the formula in cell B2 of the above spreadsheet returns the value 150.5. I.e. 2 hours 30 minutes and 30 seconds is equal to 150.5 minutes.
