time_ago_in_words NaiveDateTime.utc_now
# less than 5 seconds
time_ago_in_words ~N[2017-08-14 04:40:12.101212]
# ......

distance_of_time_in_words

from = Timex.to_datetime({{2015, 10, 31}, {0, 0, 0}})
to   = Timex.shift(from, days: 45)
distance_of_time_in_words(from, to)
# about 2 months

Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "ja")
from = Timex.to_datetime({{2015, 10, 31}, {0, 0, 0}})
to   = Timex.shift(from, months: 1)
distance_of_time_in_words(from, to)
# 約1ヶ月

Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "es")
from = Timex.to_datetime({{2015, 10, 31}, {0, 0, 0}})
to   = Timex.shift(from, months: 18)
distance_of_time_in_words(from, to)
# más de 1 año

Or uses Timex.format!("{relative}", :relative) instead, like this.

Timex.shift(datetime, hours: -3) |> Timex.format!("{relative}", :relative)
"3 hours ago"
