Wait reduced for no apparent reason

[pilkjaer]

Hi! I think the idea of this program is really nice and I would like to use it to control lights outside of the house. Time for sunrise and sunset are being correctly calculated for my location.
Unfortunately, when using example stated in the documentation it doesn't work as I expect it.
I expect program to terminate 30 min prior sunset. For some reason it terminates after 10 sec.
Below is a debug printout. Last line in debug printout is a mystery to me. Why "wait" is being reduced!?
I'm running "latest" version that I fetched and built about a week ago. Running on RPi3.

According to the code you do reduce wait to 10 sec when running in debug mode (by design). But it seems that even for "normal" mode same/similar timeout being applied.

Source code in question:

//
// In debug mode, we don't want to wait for sunrise or sunset. Wait a minute instead.
//
if (pRun->debug == ONOFF_ON)
{ printf("Debug: Wait reduced from %li to 10 seconds.\n", waitSeconds);
waitSeconds = 10;
}
else if (pRun->functionPoll == ONOFF_ON) waitSeconds += 60; // Make more sure that a subsequent POLL works properly (wink ;-)
