Add a Timer to an existing C++ Project and Load Optimizations

Hi there.... I need a Timer added on the existing Project ( [login to view URL] ) In [login to view URL] the Program uses the Timestamps squelch_open and squelch_close to calculate an inteference and to calculate the idle Time. I want a function like a Timer that closes the repeater after time x ( to define in config file ) and resets the timer only when squelch_open is greater than x seconds. So that when we have short squelch openings the timer continues running down from time x to zero, when its on zero the repeater should close. Also i want a flag to make different RogerBeeps.. one when squelch_open < x seconds and one >x seconds, so that short openings of Squelch have a different rogerBeep as long openings... The Time in seconds should be defined in the tcl config file
