C Specification

To convert from timespec monotonic time to XrTime, call:

// Provided by XR_KHR_convert_timespec_time
XrResult xrConvertTimespecTimeToTimeKHR(
    XrInstance                                  instance,
    const struct timespec*                      timespecTime,
    XrTime*                                     time);

Parameters

Parameter Descriptions
  • instance is an XrInstance handle previously created with xrCreateInstance.

  • timespecTime is a timespec obtained from clock_gettime with CLOCK_MONOTONIC.

  • time is the resulting XrTime that is equivalent to the timespecTime.

Description

The xrConvertTimespecTimeToTimeKHR function converts a time obtained by the clock_gettime function to the equivalent XrTime.

If the output time cannot represent the input timespecTime, the runtime must return XR_ERROR_TIME_INVALID.
