* NAME
* ts_granularity
*
* SYNOPSIS
* ts_granularity(int *granularity)
*
* DESCRIPTION
* The ts_granularity function is used to get the filesystem
* modtime granularity. For most operating systems, this is 1 second
* but can vary.
*
* Defaulting and clean-up are done here, also.
* If absent, defaults to 1.
