Am I the only one that thinks the name of SEC_IN_USEC, SEC_IN_MS, MS_IN_USEC, and USEC_IN_NS are somewhat missleading?

1. They are inconsistent in itself. Some abbreviate "seconds" with SEC, some with S
2. Their values reflect the opposite of their name: there are 1000000 microseconds in a second, not 1000000 seconds in a microsecond; there are 1000 milliseconds in a second, not 1000 seconds in a microsecond; etc.
