Modifying the hour in a datetime object already created

Ruby
1

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

now = DateTime.now

year, yday = now.year, now.yday
ten_hours = Rational 10, 24

tomorrow = DateTime.ordinal year, yday + 1
ten_oclock_tomorrow = tomorrow + ten_hours

y ‘now’ => now
y ‘ten_oclock_tomorrow’ => ten_oclock_tomorrow

now: 2006-09-14T11:01:49-0701

ten_oclock_tomorrow: 2006-09-15T10:00:00Z
