# PR_Now
Returns the current time.
## Syntax
```{code}
#include <prtime.h>
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()`.
