Detailed Description

This class is used to get the current system time.

Note
Should we refactor this? It seems like the SIP-timer stuff should live in resip/stack somewhere.

Member Function Documentation

◆ getForever()

static uint64_t resip::Timer::getForever ( )
inlinestatic

Infinit time in future.

Definition at line 91 of file Timer.hxx.

◆ getMaxSystemTimeWaitMs()

static unsigned resip::Timer::getMaxSystemTimeWaitMs ( void  )
inlinestatic

On windows, change getSystemTime() to not use the actual clock time returned by GetSystemTime().

The replacement time function on some versions of windows (< Vista, GetTickCount()) returns a 32-bit value, so it will rollover at some point. Any code that waits on timers should not wait longer than this value.
