I'm trying to configure inputmask to allow large and negative time values.

Examples:

• 1:10
• 10:20
• 198:45
• -20:00
• -300:01
• -0:01

I've found this for regular 24 time periods:

$("input.timeedit").inputmask({ alias: "datetime", inputFormat: "HH:mm" });

Which works great for a max 24 hours but does not go higher or allow negatives. Any suggestions on how to configure it?
