[SOLVED] How do I get a system time stamp?

Basically I want to take a time stamp. Close the game. Then when the game next opens I want to check if so much time has elapsed.

Any ideas how I can do this?

ok, partially solved. I found the rex_date plugin that allows me to do date.UnixTimestamp. So I just need to subtract one from the other to get a difference in seconds.

So now I need to work out how to tell if the player has minimized the game on a mobile platform so I know when to call it.

Any ideas?

I was wondering if there was an on resume event which is tied to pausing on unfocus?

From the manual, for the browser Object:

"On suspended

On resumed

Triggered when the page's visibility changes, or when a mobile app is going in to the background or foreground. When invisible or in the background the app is suspended: all events stop running and all audio is muted."

Cheers, I had just found it, but thanks for the confirmation
