As a side benefit, fix an (non-user-visible) bug in display_s5(). Also fixed a bug where removing orphaned pages did not expire cached summary pages.

# Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.
|
|
#
|
|
# These methods use Time#advance for precise date calculations when using from_now, ago, etc.
|
|
# as well as adding or subtracting their results from a Time object. For example:
|
|
#
|
|
# # 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://stdlib.rubyonrails.org/libdoc/date/rdoc/index.html] and
|
|
# Time[http://stdlib.rubyonrails.org/libdoc/time/rdoc/index.html] should be used for precision
|
|
# date and time arithmetic
