Michael Kerrisk improved clock_getres.2 in manpages 3.40: .B CLOCK_MONOTONIC Clock that cannot be set and represents monotonic time since some unspecified starting point. +This clock is not affected by discontinuous jumps in the system time +(e.g., if the system administrator manually changes the clock), +but is affected by the incremental adjustments performed by +.BR adjtime (2) +and NTP. Maybe one can add (please proofread my english): "This clock allow to precisely measuring time elapsed, for use in real-time programs." http://pubs.opengroup.org/onlinepubs/009604599/functions/clock_getres.html -- Simon Paillard -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
