Capturing a couple formulas for future reference. I was using restic backup stats and wanted to convert the time a job ran into hours and minutes. Also convert bytes process to TB.
bytes to TB example:
total_bytes_processed: 5773378 / 1000000000000 == 1.502888851889
duration to HH:MM example using libre calc:
total_duration: 15870.197288027 / 86400 and then Format Cell > Time > HH:MM:SS will show 04:24:30
