distance_of_time_in_words(from_time, to_time = 0, include_seconds = false, options = {}) | |
Set include_seconds to true if you want more detailed approximations when distance < 1 min, 29 secs Distances are reported based on the following table: | |
0 <-> 29 secs # => less than a minute | |
30 secs <-> 1 min, 29 secs # => 1 minute | |
1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes | |
44 mins, 30 secs <-> 89 mins, 29 secs # => about 1 hour | |
89 mins, 29 secs <-> 23 hrs, 59 mins, 29 secs # => about [2..24] hours | |
23 hrs, 59 mins, 29 secs <-> 47 hrs, 59 mins, 29 secs # => 1 day | |
47 hrs, 59 mins, 29 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days | |
29 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 1 month | |
59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months | |
1 yr <-> 1 yr, 3 months # => about 1 year | |
1 yr, 3 months <-> 1 yr, 9 months # => over 1 year | |
1 yr, 9 months <-> 2 yr minus 1 sec # => almost 2 years | |
2 yrs <-> max time or date # => (same rules as 1 yr) | |
With include_seconds = true and the difference < 1 minute 29 seconds: | |
0-4 secs # => less than 5 seconds | |
5-9 secs # => less than 10 seconds | |
10-19 secs # => less than 20 seconds | |
20-39 secs # => half a minute | |
40-59 secs # => less than a minute | |
60-89 secs # => 1 minute | |
Examples | |
from_time = Time.now | |
distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour | |
distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour | |
distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute | |
distance_of_time_in_words(from_time, from_time + 15.seconds, true) # => less than 20 seconds | |
distance_of_time_in_words(from_time, 3.years.from_now) # => about 3 years | |
distance_of_time_in_words(from_time, from_time + 60.hours) # => about 3 days | |
distance_of_time_in_words(from_time, from_time + 45.seconds, true) # => less than a minute | |
distance_of_time_in_words(from_time, from_time - 45.seconds, true) # => less than a minute | |
distance_of_time_in_words(from_time, 76.seconds.from_now) # => 1 minute | |
distance_of_time_in_words(from_time, from_time + 1.year + 3.days) # => about 1 year | |
distance_of_time_in_words(from_time, from_time + 3.years + 6.months) # => over 3 years | |
distance_of_time_in_words(from_time, from_time + 4.years + 9.days + 30.minutes + 5.seconds) # => about 4 years | |
to_time = Time.now + 6.years + 19.days | |
distance_of_time_in_words(from_time, to_time, true) # => about 6 years | |
distance_of_time_in_words(to_time, from_time, true) # => about 6 years | |
distance_of_time_in_words(Time.now, Time.now) # => less than a minute |
