C Specification

To convert from timespec monotonic time to XrTime, call:

XrResult xrConvertTimespecTimeToTimeKHR(
    XrInstance                                  instance,
    const struct timespec*                      timespecTime,
    XrTime*                                     time);

Parameters

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

  • unixTime is a timespec obtained from clock_gettime with CLOCK_MONOTONIC.

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

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 unixTime, the runtime must return XR_ERROR_TIME_INVALID.
