Get the hours and minutes until 10am the next day

In Rails, how can I calculate the time until 10am the next day, and report it in hours and minutes?

For example, if it was 11:30pm, I would get "10 hours 30 minutes"?

Things I'm trying:

// Get the right day 

if (**before 10am**)
  days = Time.now
else
  days = Time.now + 1.days

//

Try creating a time variable. The following is not neat but is workable. 

tomorrow_10_am = Time.new((Date.today + 1).year,
                          (Date.today + 1).month,
                          (Date.today + 1).day,
                          10
                          )
time_calculation = ((tomorrow_10_am - Time.now)/1.minute).round
result = (time_calculation / 60).to_s + " hours " + (time_calculation % 60).to_s + " minutes"

# the result is the time difference in hours and minutes format

You cannot get the precise format you want using just Rails (ActiveSupport + ActiveView that is) but you can get close:

time_now = Time.zone.now
time_tomorrow_at_10 = Time.zone.tomorrow.at_beginning_of_day.advance(hours: 10)

distance_of_time_in_words(time_now, time_tomorrow_at_10) # => about 24 hours

Note that the usage of Time.now is almost always incorrect as it doesn't take your app's configured time zone into account.

Rails doesn't have precise helper for that. If you use distance_of_time_in_words(from_time, to_time), it will return rough estimation:

distance_of_time_in_words(Time.now, Date.tomorrow + 10.hours)
#=> "1 day"

So you can use this gem to get really precise time.

time_ago_in_words(Date.tomorrow + 10.hours)
#=> "22 hours, and 30 minutes"
