Clean up time handling code
base/str.hh: this should really be inline base/time.cc: base/time.hh: clean up how the time class works. Export only one, and let people calculate their own elapsed times, etc. sim/main.cc: sim/sim_time.X -> base/time.X --HG-- rename : sim/sim_time.cc => base/time.cc rename : sim/sim_time.hh => base/time.hh extra : convert_revision : f3888fe3a1fdd1022084c282b58407c631a6d9a0
