Suspend execution of the current thread until the specified `absoluteTime`, or an interrupting signal is received. Optionally specify `clockType` which determines the epoch from which the interval `absoluteTime` is measured (see {Supported Clock‐Types} in the component documentation). The behavior is undefined unless `absoluteTime` represents a time after January 1, 1970 and before the end of December 31, 9999 (i.e., a time interval greater than or equal to 0, and less than 253,402,300,800 seconds). Note that the actual time suspended depends on many factors including system scheduling and system timer resolution.
