mclock {nanonext}

Clock Utility

Description

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()

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().

Value

A double.

Examples

time <- mclock(); msleep(100); mclock() - time
