unblockTime

removes blocking set by the blockTime() method

void unblockTime(any days, [array zones,object sections] );

Deprecated

instead of it, you can use deleteMarkedTimespan

var spanID = scheduler.addMarkedTimespan({  
    days:  [0,1], 
    zones: "fullday"              
});
scheduler.deleteMarkedTimespan(spanID);

days	any	(Date, number,array, string) days that should be limited
zones	array	the period in minutes that should be limited. Can be set to 'fullday' value to limit the entire day
sections	object	allows blocking date(s) just for specific items of specific views. BTW, the specified date(s) will be blocked just in the related view(s)

Example

var spanId = scheduler.blockTime(new Date(2013,2,5), "fullday");
...
//cancels blocking from 0 till 8 and from 18 till 24 hours for February 5, 2013
scheduler.unblockTime(new Date(2013,2,5), [0,10*60]);
