15// The default local time HAL module. The default module simply uses the
16// system's clock_gettime(CLOCK_MONOTONIC) and does not support HW slewing.
17// Devices which use the default implementation should take care to ensure that
18// the oscillator backing the CLOCK_MONOTONIC implementation is phase locked to
19// the audio and video output hardware. This default implementation is loaded
20// if no other device specific modules are present. The exact load order can be
21// seen in libhardware/hardware.c
22//
23// The format of the name is local_time.<hardware>.so
