This song is a continuation of Robin detailing his relationship with Skye. But stripping it back to a simple music analogy: that if they are on stage together, they will “keep time” and help each other play in unison. The larger metaphor is that they each will ensure that they do their respective parts in the relationship to ensure that a fallout doesn’t occur again.

An alternative explanation is that the song describes the inevitable cycle of emotions, highs and lows, that the author goes through as he lives his life. By this point in his life he has the perspective to realize that every rise includes a certain, inevitable fall, almost like clockwork. Having accepted that, what to do with that knowledge? How can it be useful? Perhaps the cycle is so consistent that someone could keep time against it, if they needed to for survival. So he offers his cycle to others who experience emotional instability/confusion to orient themselves, hoping they will do the same for him when he is lost again.
