How to do hour and time format restriction for inputText

The below code required for the time format restriction to restrict the time for up to 23:59

<af:inputText label="" id="time" simple="true" value="" contentStyle="width:30px;"                  maximumLength="5">

<af:validateRegExp pattern="([01][0-9]|2[0-3]):[0-5][0-9]" messageDetailNoMatch="Time   Format must match HH:MM" hint="Time Format: HH:MM"/>

</af:inputText>
