Treat 24:00 as an equivalent of 00:00

We have users entering punch in / punch out times into a timesheet and we use this great inputmask library with a basic 'h:s' mask.

Users can enter in/out times like '08:30' - '17:00', which works great.

When the user works a night shift and started working before midnight and finishes after midnight he enters time like so '23:00' - '06:00' (for example Monday night 23:00 until Tuesday morning 06:00)

In cases where we don't allow time entry that passes into the next day we currently set the 'punch out' time to '00:00', signifying the user can only enter time until midnight. So '23:00' - '06:00' gets truncated to '23:00' - '00:00'. (Some customers' back-end systems don't allow timespans across multiple days)

We would like to truncate to '24:00' so it becomes clear to the user they entered a valid punch out time but the system doesn't allow more than 24:00 hours.

If i simply set the input field value like this j$(element).val('24:00') the input field value becomes '20:0_' instead of '24:00'.

I understand 24:00 is not exactly a valid moment in time but for a nicer user experience it would be great to allow this input and treat it as '00:00'

Thanks for reading this far, can't wait to get some thoughts on this.

Start with the basic h:s time mask and reproduce setting the field to 24:00, which currently becomes 20:0_. The work is done when 24:00 is accepted and treated as equivalent to 00:00 while preserving the requested user-facing value.
