Provides the number of elapsed milliseconds since an arbitrary reference time
in the past. The reference time will be the same for a given session, but
may differ between sessions.
Usage
mclock()
Arguments
Value
A double.
Details
A convenience function for building concurrent applications. The
resolution of the clock depends on the underlying system timing facilities
and may not be particularly fine-grained. This utility should however be
faster than using Sys.time().
