Subject: When the clock is frozen, set delta time to 0 so that the subsystems
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=c5425590975dbbebd83916db17b3a1996f506e16;p=flightgear.git

When the clock is frozen, set delta time to 0 so that the subsystems
won't keep updating themselves; that effectively freezes the
instrumentation.
