* Improve ActiveSupport::TimeWithZone conversion to YAMLAndrew White2015-04-221-0/+9
| | | | | | | | | | | Previously when converting AS::TimeWithZone to YAML it would be output as a UTC timestamp. Whilst this preserves the time information accurately it loses the timezone information. This commit changes that so that it is saved along with the time information. It also provides nicer encoding of AS::TimeZone instances themselves which previously embedded all of the data from the TZInfo records. Fixes #9183.
* Refactor ActiveSupport::Timezone#strptimeAndrew White2015-04-221-28/+35
| | | | | Make strptime behave more like parse when components are missing and share behavior between the two methods.
* Add ActiveSupport::TimeZone#strptime.Paul A Jungwirth2015-04-221-0/+20
| | | | This makes it easier to parse user-inputted times as from a given time zone.
* Revert "Take DST into account when locating TimeZone from Numeric."Andrew White2015-03-091-7/+1
| | | | | | | | | | | | | | | | Reverting this as it's not the implementation that we would like it to be. This is being used inside of ActiveSUpport::TimeZone[] and it's unaware of the context in which to find the timezone period so the timezone found changes depending on whether DST is in effect for the current period. This means that `'2001-01-01'.in_time_zone(-9)` changes from winter/summer even though it's the same date that we're trying to convert. Since finding timezones by numeric offsets is a bit hit and miss we should introduce a new API for finding them which supplies the date context in which we want to search and we should probably also deprecate the finding of timezones via the [] method, though this needs further discussion. This reverts commit 2cc2fa3633edd96773023c6b09d07c7b9d9b841d.
* Take DST into account when locating TimeZone from Numeric.Yasyf Mohamedali2015-03-031-1/+7
| | | | | | When given a specific offset, use the first result found where the total current offset (including any periodic deviations such as DST) from UTC is equal.

* Use directly TZInfo::Timezone without proxybrainopia2015-01-041-2/+2

* reduce object allocations in utc_offsetAaron Patterson2014-08-291-2/+2
| | | | | | `try` allocates an array on every call, we should avoid calling it in hotspots. This reduced AttributeMethodsTest#test_setting_time_zone_aware_attribute_with_string from 18k allocations to 14k

* Make TimeZone#parse behave more like Time#parse.Ulysse Carion2014-05-111-1/+12
| | | | | Namely, if the mday is omitted but any other upper components are, then instead of supplying the mday from the current time, it defaults to 1.
* make tests pass on Ruby 2.2Aaron Patterson2014-03-131-1/+1
| | | | | | Apparently we've been using a buggy feature for the past 6 years: https://bugs.ruby-lang.org/issues/9593
* Maintain current timezone when changing time during DST overlapAndrew White2014-01-261-0/+4
| | | | | | | | | | | | | | Currently if a time is changed during DST overlap in the autumn then the method `period_for_local` will return the DST period. However if the original time is not DST then this can be surprising and is not what is generally wanted. This commit changes that behavior to maintain the current period if it's in the list of periods returned by `periods_for_local`. It is possible to alter the behavior of `period_for_local` by specifying a second argument but since we may be change from another time that could be either DST or not then this would give inconsistent results. Fixes #12163.

* Don't lazy load the tzinfo libraryAndrew White2014-01-011-19/+2
| | | | | | | | | Lazy loading the tzinfo library doesn't really buy us anything because the gem is installed as a dependency via the gemspec and if a developer is using Active Support outside of Rails then they can cherry pick which files to load anyway. Fixes #13553

* | Add support for localized date referencesColin Bartlett2013-12-031-0/+10
| | | | | | | | | | | | | | Ruby's Date class automatically gives us #yesterday, #today, and #tomorrow. And ActiveSupport has a handy Time.zone.today for getting a localized version. But there was no localized version of #yesterday or #tomorrow. Until now.

* Deprecate obsolete Time to DateTime fallback methodsAndrew White2012-12-111-1/+1
| | | | | | | The Time.time_with_datetime_fallback, Time.utc_time and Time.local_time methods were added to handle the limitations of Ruby's native Time implementation. Those limitations no longer apply so we are deprecating them in 4.0 and they will be removed in 4.1.
* Replace comments' non-breaking spaces with spacesclaudiob2012-12-041-1/+1
| | | | | | | | | | Sometimes, on Mac OS X, programmers accidentally press Option+Space rather than just Space and don’t see the difference. The problem is that Option+Space writes a non-breaking space (0XA0) rather than a normal space (0x20). This commit removes all the non-breaking spaces inadvertently introduced in the comments of the code.
* Only take the date parts from Time.zone.nowAndrew White2012-12-011-3/+3
| | | | | | | When there are missing components in the Hash returned by Date._parse only the date components should default to the value of Time.zone.now, the time components should all default to zero.
* Make `Time.zone.parse` to work with JavaScript date stringsAndrew White2012-12-011-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chrome, Safari and Firefox serialize Date objects to strings such as 'Mon May 28 2012 00:00:00 GMT-0700 (PDT)'. When these strings are parsed the zone is interpreted as 'GMT-0700' which doesn't exist in the TzInfo list of timezones. By taking advantage of the improved date/time handling in 1.9.3 we can use `Date._parse` and the `:offset` value which is parsed correctly. Three tests were amended to make them pass: 1. test_parse_with_old_date This needed changing to a different value because the original value was before EST was adopted so was being changed to a LMT (Local Mean Time) value after the change. It didn't before because `DateTime` just has offsets from UTC not timezones. 2. test_parse_should_not_black_out_system_timezone_dst_jump Changed the implementation of this test as the stubs were dependent on internal implementation details of the test. Confirmed that the modified test still failed when the implementation of `parse` was restored to pre-#5571. 3. test_parse_should_black_out_app_timezone_dst_jump Ditto. Closes #5770.
