Use the monotonic system clock as the clock against which the `absTime` timeouts passed to the `timedWait` methods are interpreted (see {Supported Clock‐Types} in the component‐level documentation). This method does not return normally unless there are sufficient system resources to construct the object. == Synopsis Declared in `<bslmt_timedsemaphore.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- explicit TimedSemaphore(std::chrono::steady_clock const&); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
