Provides high-precision timing using the system's monotonic clock, which is not affected by system clock adjustments and is suitable for measuring elapsed time in real-time applications. cCs d|_dS)z¹Initialize the system clock. The clock starts in an uninitialized state and must be started explicitly using the start() method before time measurement begins. rN)Ú_time©Úself©rúO/home/ubuntu/.local/lib/python3.10/site-packages/pipecat/clocks/system_clock.pyÚ__init__s zSystemClock.__init__ÚreturncCs|jdkr t ¡|jSdS)zÏGet the elapsed time since the clock was started.
