:relfileprefix: ../../../
:mrdocs:

Block until the count of this semaphore is a positive value, or until the specified `absTime` timeout expires. `absTime` is an _absolute_ time represented as an interval from some epoch, which is determined by the clock indicated at construction (see {Supported Clock‐Types} in the component documentation). If the `absTime` timeout did not expire before the count attained a positive value, atomically decrement the count and return 0; otherwise, return a non‐zero value with no effect on the count.
