Current Behavior

Phase 1 of a logical switch timer takes 1 cycle (100ms) longer than expected (0.1s longer than v1 value).

Expected Behavior

Timer intervals are interpreted correctly.

Steps To Reproduce

1. Create a logical switch L1 with type=timer and v1=v2=0.1s
2. Create a global var that increments when L1 is set
3. Use a stopwatch to measure L1 timer cycle time
4. Measured cycle time is 0.3s where you would expect it to be 0.2s.

Anything else?

In switches.cpp:logicalSwitchesTimerTick, there's code to handle v1->v2 transition

else if (*lastValue < 0) {
          if (++(*lastValue) == 0)
            *lastValue = lswTimerValue(ls->v2);
        }

but when going in the opposite direction, it takes an extra cycle to get from lastValue==1 to reloading v1 into lastValue.
