While working on strftime I noticed some constants were being defined in unexpected places. One thing led to another, and I ended up doing a major cleanup of the time functions. What's included: All uses of <time.h> in /src and /test removed (except for LibcTest.cpp) The various time constants have been moved to time_constants.h, and the `time_constants` namespace. struct tm gets its own type indirection header now.
