[marto]: good morning all, TCIF
[gnosti]: I'm reading from ffmpeg lengths of video clips in H:M:S and needing to add them and format them back to H:M:S for feeding back to ffmpeg
[marioroy]: kcott Thanks
[Corion]: gnosti: I would cheat and use my approach instead of dealing with durations as objects, or a module
[Corion]: You could even do the calculation directly - my $duration = $H * 3600+ $M*60 + $S; strftime '%H:%M:%S', timelocal($duratio n)
[Corion]: (and that strftime call is largely superfluous too, converting back to H:M:S isn't hard either)
