Time Column

(pardon the crosspost… I posted this on rubyonrailsforum.com, too but
it doesn’t seem to get as much traffic.)

I’ve got a project that I’m working on where I’m tracking band
performances.

So, I’ve got a model for “Show” and it’s got a date associated with it.
But I’ve got other fields that I’d like to set times for, but not worry
about the date.

like this:

show_date (date)
doors_open (time)
show_starts (time)
check_in (time)
load_in (time)
etc…

how would I go about doing that?

Thanks!
