In version 1.x, the constants were defined in the global namespace so it was responsible to explicitly check that, for instance, `HOUR_IN_SECONDS` was not already defined before attempting to define it. Now that the constants are namespaced, this just adds unnecessary overhead: if someone else is defining constants in the `TimeConstants` namespace, there are bigger problems. Additionally, IDEs seem to trip over the `defined()` checks, not being sure that the constants exist. They do. Similarly, while it was fun writing the intial constants in a way that they build upon each other, there's really no reason that this file should have to confirm (for example) that 24 hours * 60 minutes/hour = 1440 minutes/hour. These values do not change (hence *constants*), so save a little bit of basic multiplication by hard-coding the values.

defined()checks and unnecessary multiplication in order to a) help IDEs and b) remove an (albeit tiny) level of overhead (Skip defined() checks, unnecessary multiplication #21)
