Hi there,
Does anyone have any experience of setting up a timer which doesn’t
rely on the system real time clock ? I basically want to have a simple
timeout function on some hardware interfaces. However, there’s a
possibiblity that simultaneously the user, or application software, may
update the realtime clock. The native (POSIX) timer functions all
appear to rely on the hardware RTC and can cause mayhem, as expected,
if the real time clock is adjusted.
Any thoughts greatfully received.

No they don`t rely on the RTC hardware they rely on the internal time
that is kept by the OS.
If you setup your timer to work in relative mode you should be fine.
Any thoughts greatfully received.
