Time played?

Hi all, I’m trying to work out how much Halo 3 I have played as I only just synced my profile by loading up H3 and playing a game of it. I know it is a lot but I’m not 100% sure how the numbers work, can anyone shed some light for me please?

I’m not sure what each number represents in 38.19:22:35.

Is it 38 days, 19 hours, 22 minutes and 35 seconds?

Sorry if this is the wrong place to ask, how long have you played the legacy Halo games for??

Sadly I’ve gone by many names since the release of halo 3 because I easily get bored of the same name and challenge myself after making one in multiple scenarios. And I don’t have the time to calculate over 30+ tags of games played. I know, it ridiculous and I’m not happy with myself. But we’ll over 100 days.

there was even a time back in Xbox forum days where you could compare your time played with the entire forum community. Needless to say, there was a 300 hour gap between the halo community on the Xbox forums as a whole and JUST ME. Meaning I played 300+ hours MORE than the halo Xbox forums community.
