Hi!
I have written a piece of scheduling code that executes at given times and then when the last give time is done, sleeps until the end of day, skips to the next day and re-starts the schedule…
For the first time yesterday two separate command windows on Windows 10 running this scheduler froze or didn’t wake up passing from 24th of June to 25th of June…
Since this happened on both separate programs running in different command windows I find it a bit suspicious…
my PC did not freeze as other programs were running fine. The only way to unfreeze was to kill using Crtl+C… No major problem there but I don’t like loose suspicious ends…
Could I have ‘unfrozen’ these programs in another way to continue normally?
Is there something odd in my code?
Is there something special about going from 24th of June to 25th of June?
Screen output and relevant code below… any comments suggestions are welcome!
