Subject: modifying the hour in a datetime object already created

In my prog, I create a datetime object

d1s = DateTime.civil(2006,6,5,16,00,00)

then later on, I need to create another datetime from this one by 
adding 1 day and changing the hour to 10:00:00

I can do  easily

d1e = d1s + 1

but how can I modify the hour, which stays at 16:00:00 ?

thanks for your help
