* AUTHORS:
*
* mario.kleiner.de@gmail.com mk
*
* PLATFORMS: GNU/Linux Only
*
* PROJECTS: All
*
* HISTORY:
*
* 2/20/06 mk Wrote it. Derived from Windows version.
* 1/03/09 mk Add generic Mutex locking support as service to ptb modules. Add PsychYieldIntervalSeconds().
*
* DESCRIPTION:
*
* Functions for querying system time and for waiting for either a
* specified amount of time or until a specified point in time.
* Also returns timer ticks and resolution of timers.
