     29 Description
     30 -----------
     31 
     32 ``PR_Now()`` returns the current time as number of microseconds since
     33 the NSPR epoch, which is midnight (00:00:00) 1 January 1970 UTC.
     34 
     35 You cannot assume that the values returned by ``PR_Now()`` are
     36 monotonically increasing because the system clock of the computer may be
     37 reset. To obtain monotonically increasing time stamps suitable for
     38 measuring elapsed time, use ``PR_IntervalNow()``.
