Hourglasses, sundials, clocks, and calendars have all been methods we use to keep track of time. With a check of the watch (or smartphone) we can know whether we’re running late or we have time for a coffee stop. But timing things right isn’t always a conscious decision, or a trivial one. Organisms need to know when to hunt, migrate, hibernate, mate, molt, and flower, to list a few.
Here we look at time through multiple lenses, because meaningful information that winds one organism’s “clock” may be extracted differently than that information which winds another’s.
