`DateTime#getlocal` is newly added public API.
It's responsible is same as `DateTime#utc`, so `calculations.rb` is
a best plase to define this method.
For keeping consistency with `DateTime#utc`, defines `#localtime` and
defines `getlocal` as an alias method.

In Ruby 2.4 the `to_time` method for both `DateTime` and `Time` will
preserve the timezone of the receiver when converting to an instance
of `Time`. Since Rails 5.0 will support Ruby 2.2, 2.3 and later we
need to introduce a compatibility layer so that apps that upgrade do
not break. New apps will have a config initializer file that defaults
to match the new Ruby 2.4 behavior going forward.
For information about the changes to Ruby see:
https://bugs.ruby-lang.org/issues/12189
https://bugs.ruby-lang.org/issues/12271
Fixes #24617.

The native DateTime#<=> implementation can be used to compare instances
with numeric values being considered as astronomical julian day numbers
so we should call that instead of returning nil.
Fixes #24228.
|
|
|
|
|
| |
Because `DateTime` inherits `Date` and `Date` includes `DateAndTime::Zones`,
`DateTime` not need to include `DateAndTime::Zones` again.

Output of `formatted_offset` is depends on input so it’s not always in +HH:MM format. Possible outputs are “+5:30”, “+530” or provided alternate UTC string [ci skip]

The concept of a blank date or time doesn't make sense so we can short
circuit the calls for `blank?` on these classes to gain small speed boost.

Previously this method always returns `.0` in the fractional part. This commit
changes it to preserve the fractional seconds instead.

Added partial days support to `DateTime`'s `advance` method.
|
| |
| |
| |
| |
| | |
You can now add partial days (e.g. 2.5.days) to `DateTime` with the advance method.
This was acheived by mimicing the `advance` implementation in `Time`.

Similar implementations of #in_time_zone exists for Date, Time and DateTime so
method is extracted into its own module. Also some logic is extracted into
private method.
|
|
|
|
|
|
| |
Methods: :past? and :future? are already defined identically
in date_and_time/calculations.rb which is included in Date.
Because DateTime is a subclass of Date, it can call them.

Added Time#middle_of_day method

Added middle_of_day method to Date and DateTime

Use a lambda to ensure that the generated string respects the offset of
the time value. Also add DateTime#to_s(:iso8601) and Date#to_s(:iso8601)
for completeness.
|
| |
| |
| |
| |
| |
| |
| |
| | |
If the DateTime core extensions were loaded before the Date core extensions
then you would get a superclass mismatch as DateTime hasn't been defined
yet so it gets set to Object by the acts_like core extension.

Add `DateTime#usec` and `DateTime#nsec` so that `ActiveSupport::TimeWithZone`
keeps sub-second resolution when wrapping a `DateTime` value.

Date, DateTime, Time and TimeWithZone can now be compared to infinity,
so it's now possible to create ranges with one infinite bound and
date/time object as another bound.
Ex.: @range = Range.new(Date.today, Float::INFINITY)
Also it's possible to check inclusion of date/time in range with
conversion.
Ex.: @range.include?(Time.now + 1.year) # => true
@range.include?(DateTime.now + 1.year) # => true
Ability to create date/time ranges with infinite bound is required
for handling postgresql range types.

Calculate the seconds since the UNIX epoch using the difference in
Julian day numbers from the epoch date. By reducing the Rational math
to just the offset component this gives a significant improvement.

There appears to be a bug with DateTime#strftime("%s") on 32-bit platforms.
Bug report: http://bugs.ruby-lang.org/issues/6683
This reverts commit 210cd756a628cc19c0d6e44bee8c33dfb2d9d598.

Currently if the offset is not zero then to_time returns self which
can lead to errors where a developer assumes that the value is a
Time. To solve this we can use the native implementation of
DateTime#to_time in Ruby 1.9.3 as it handles offsets properly and
is faster than our override.

The native implementation of the seconds since the UNIX epoch in
strftime is significantly faster than our method.
Benchmark:
----------
require 'benchmark/ips'
require 'date'
require 'time'
date = DateTime.civil(1253,7,6,20,4,0)
Benchmark.ips do |x|
x.report("strftime.to_i") { date.strftime('%s').to_i }
x.report("ssue.to_i") { ((date - DateTime.civil(1970)) * 86400).to_i }
x.report("strftime.to_f") { date.strftime('%s').to_f }
x.report("ssue.to_f") { ((date - DateTime.civil(1970)) * 86400).to_f }
end
Output:
