I don't think you need a legal policy or regulation to determine the "maximum time to report in". If you're recalled, the amount of time should be as little as it required. If you're out having dinner, it's the time required to pay your bill, drive home, drop off the wife, and get to the unit.
Further to this, COs are well within their perogative to amplify exisiting regulations and orders through RO, SOs, and SOPs. If the CO of a unit says that any personnel going out of area (such as flying all the way to Toronto from Calgary on a weekend) are required to obtain permission from their chain of command fill out a leave pass, then that is a legal order and you can suffer the consequences if you choose to ignore it.
