ESSID with time schedule doesn't respect the schedule

[marius_negrea]

I have defined a ESSID with a time schedule ( it should be active between 06:00 up to 24:00) but somehow it's getting active at 05:00 and suspends at 23:00 o'clock.
I have checked the system clock on both primary and secondary ZD (3050 model) and they are o.k. Do you have any idea?
