Time is a very simple construct. Someone asks you what time it is; you glance at your watch, and tell them. "It's a quarter to five." Or you might say, "It's four-forty-three," to give a little more precision. Or maybe "four-forty-three PM" or "sixteen-forty-three." Maybe "four-forty-three PM Eastern Daylight Time" would be more precise, though possibly less helpful if the other person was in a different time zone and it was a time of year when daylight savings time wasn't in effect.

Time is a deceptively complex construct.

Reference Point

Testability

Precision

It's possible to have too much precision.

Time comparisons

Is "May 5, 2006" before, after, or equal to "8:00 AM, May 5, 2006"?
