Can I get some clarity?

Parents were supposed to fly UA 1999 tonight - DEN-DTW. Inbound plane diverted to CYS due to weather, and arrived at Denver about 3 hrs late.

My parents called me and told me the flight was cancelled due to crew time out (they aren't travel savvy at all, so they would only tell me that if they were told that). I tell them to get in (the very long) Denver CS line and I will get their flights rebooked while they try to get a hotel and food voucher.

I get them rebooked tomorrow morning on Delta. They tell me CS tells them they see I got them the DL flights, but it was a weather delay that caused the pilots to time out, so it was a weather delay and thus no hotels and no vouchers. They are just going to stay in the terminal overnight. I know weather = no vouchers, but this was a crew time out...or if a weather causes a crew timeout, it's still not valid?
