About time compare

Rails
1

I have a submmited date param whose data type is date and want to use
the Time object and the date param to judge if the date param passes the
today. I use the following codes judging:
#########
date.yday-Time.now.yday<0
##########
But i do not know if this code is right.Anyone tell me?

You could use the to_date method to compare the actual dates (or use
change(:hour =>0) which discard the hour minute and seconds components)
