A question about parking

[PrettyCandles]

My parents live opposite a school on a road with Residents' Parking/meter parking. The school has yellow zig-zags outside the school gates, with a plate that says you mustn't park on the zigzags at certain hours - something like Mon-Fri, 8.30am-9.30am and 3pm-4pm. The Controlled Parking areas have signs restricting parking in the marked bays to Mon-Fri 9am-6pm. All other areas are yellow-lined, so obviously you can't park there. But does this mean that you can park with impunity on the yellow zigzags Mon-Fri 9.30am-3pm and 4pm-6pm?

This says to keep the school entrance clear and The Highway Code says to "Keep entrance clear of stationary vehicles, even if picking up or setting down children".

I know the principle behind the roadmarkings, but the sign over the zigzags specifically states not to stop over them during certain hours - what about the times outside those hours? As the Highway Code site states, "The times at which the restrictions apply...are shown on nearby plates or on entry signs to controlled parking zones. If no days are shown on the signs, the restrictions are in force every day including Sundays and Bank Holidays" which implies that the zigzags are not 'active' at all times.

Call your community police officer. Or your local council traffic control, depending on who is going to be issuing parking tickets/towing vehicles?
