** Description: API to interval timing functions of NSPR.
|
|
**
|
|
**
|
|
** NSPR provides interval times that are independent of network time
|
|
** of day values. Interval times are (in theory) accurate regardless
|
|
** of host processing requirements and also very cheap to acquire. It
|
|
** is expected that getting an interval time while in a synchronized
|
|
** function (holding one's lock).
