Alter sleep behaviour for date()HEADmaster

// Previously this status would sleep all the way until the next day.
// This worked fine until the device entered sleep/hibernation
//
// Therefore a limit was added. Not the ideal solution,
// as if the device is woken within config.MaxSleep,
// then the date will not update until some extra time has elapsed.
//
// TODO: a better solution
if (until > config.MaxSleep) {
	until = config.MaxSleep
}

time.Sleep(until)
