class Integer
# Enables the use of time calculations and declarations, like <tt>45.minutes +
# 2.hours + 4.years</tt>.
#
# These methods use Time#advance for precise date calculations when using
# <tt>from_now</tt>, +ago+, etc. as well as adding or subtracting their
# results from a Time object.
#
# # equivalent to Time.now.advance(months: 1)
# 1.month.from_now
#
# # equivalent to Time.now.advance(years: 2)
# 2.years.from_now
#
# # equivalent to Time.now.advance(months: 4, years: 5)
# (4.months + 5.years).from_now
#
# While these methods provide precise calculation when used as in the examples
# above, care should be taken to note that this is not true if the result of
# +months+, +years+, etc is converted before use:
#
# # equivalent to 30.days.to_i.from_now
# 1.month.to_i.from_now
#
# # equivalent to 365.25.days.to_f.from_now
# 1.year.to_f.from_now
#
# In such cases, Ruby's core
# Date[http://ruby-doc.org/stdlib/libdoc/date/rdoc/Date.html] and
# Time[http://ruby-doc.org/stdlib/libdoc/time/rdoc/Time.html] should be used for precision
# date and time arithmetic.
