Subject: Fixed error in rtt/rta calculation in case of system clock problems
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5f673084513315690179009e9aad6420e161f030;p=nagiosplug.git

Fixed error in rtt/rta calculation in case of system clock problems

Time differences are now set to 0 in case of backward timejumps so there are no wrap-around problems any more.
The RTA calculation hopefully gets a more accurate value in these cases also.
