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:
There are 86,400 seconds in one 24-hour day.86,400 because there are 24 hours in one day and each hour has 60 minutes and each minute has 60 seconds so 24 hours times 60 minutes equals 1440 times 60 seconds equals 86,400.However, a sidereal day (Earth's rotational period) is slightly shorter. The sidereal day is 86164.0916 seconds long.
