 // Time represents an absolute point in time, internally represented as
 // microseconds (s/1,000,000) since a platform-dependent epoch.  Each
 // platform's epoch, along with other system-dependent clock interface
 // routines, is defined in time_PLATFORM.cc.
 //
 // TimeDelta represents a duration of time, internally represented in
 // microseconds.
 //
 // TimeTicks represents an abstract time that is always incrementing for use
 // in measuring time durations. It is internally represented in microseconds.
 // It can not be converted to a human-readable time, but is guaranteed not to
 // decrease (if the user changes the computer clock, Time::Now() may actually
 // decrease or jump).
 //
 // These classes are represented as only a 64-bit value, so they can be
 // efficiently passed by value.
