Time came a-creeping
Oh and time's a loaded gun

from Coldplay – Life in Technicolor ii Lyrics on Rap Genius

Meaning

We only have a limited amount of time on this earth, and if we’re not careful in how we use the time given to us it can be akin to playing with a loaded gun (and result in emotional/spiritual injuries to ourselves or to other people)
