The timebase defines how MX Foundation processes and returns the time values.
The timebase is set on a process basis using the mxfSystemTimeBaseSet() function.
The table below lists the different timebases available;
| Time Base Constant | Description | Unit |
|---|---|---|
| MXF_TIMEBASE_DEVICE_USEC | Elapsed time since the device power up (FlexMAX) or power up/reset for all others | µs |
| MXF_TIMEBASE_COMPUTER_USEC | Elapsed time since January 1, 1970 based on the computer time | µs |
| MXF_TIMEBASE_IRIGB_USEC | Elapsed time since January 1, 1970 based on the IRIG-B input | µs |
| MXF_TIMEBASE_DEVICE_NSEC | Elapsed time since the device power up (FlexMAX) or power up/reset for all others | ns |
| MXF_TIMEBASE_COMPUTER_NSEC | Elapsed time since January 1, 1970 based on the computer time | ns |
| MXF_TIMEBASE_IRIGB_NSEC | Elapsed time since January 1, 1970 based on the IRIG-B input | ns |
If the timebase is not set by an application at startup, the default timebase after a system reset is MXF_TIMEBASE_DEVICE_NSEC.
The following sections describe each timebase into more details:
