# PR_Now Returns the current time. ## Syntax ```{code} #include PRTime PR_Now(void); ``` ### Parameters None. ### Returns The current time as a {ref}`PRTime` value. ## Description `PR_Now()` returns the current time as number of microseconds since the NSPR epoch, which is midnight (00:00:00) 1 January 1970 UTC. You cannot assume that the values returned by `PR_Now()` are monotonically increasing because the system clock of the computer may be reset. To obtain monotonically increasing time stamps suitable for measuring elapsed time, use `PR_IntervalNow()`.
