Time::Zone

A very simple time-zone library which works by manipulating the TZ environment variable.

tzinfo has an antiquated view of Time. It returns local time values with a UTC time zone which is pretty much wrong.

Add this line to your application's Gemfile:

gem 'time-zone'

And then execute:

$ bundle

Or install it yourself as:

$ gem install time-zone

There are two basic use cases, getting the current time, and converting times.

Time::Zone.now("Pacific/Auckland")
=> 2018-05-25 14:09:40 +1200

Time::Zone.convert(Time.now.utc, "Pacific/Auckland")
=> 2018-05-25 14:14:22 +1200

Time::Zone.with("US/Pacific") do
	# Be aware that in some cases Time values are lazy initialized, so you need to use #localtime to force them to evaluate and use the current `TZ`.
	time = Time.new.localtime
	puts time.inspect
	# => 2018-05-24 20:32:29 -0700
end

This implementation manipulates the per-process TZ environment variable. This means that if you don't put locking around all your usage of localtime, you may end up with strange results (i.e. in a timezone other than the system specified TZ). In the future, this requirement may go away.

This library is unlikely to work on Windows because it doesn't correctly handle changes to TZ.
