It is important to keep in mind that in “general-purpose” mode, the 20 millisecond time interval is by definition approximate (although kept as accurate and consistent as possible). Unlike GPS-based mode, the timing is based entirely upon local processor clock sources, etc., and can (and probably will) | It is important to keep in mind that in “general-purpose” mode, the 20 millisecond time interval is by definition approximate (although kept as accurate and consistent as possible).
