timezones.rb

# There is some interesting magic going on regarding time zones in Rails, even more
# so in Rails 3. The easiest is to talk in UTC to your database and any other service
# you might consume, but we're stuck with a legacy schema that stores Irish time
# without time zone information.
#
# With these settings, ActiveRecord assumes that what is in your DB is in local time,
# and the local time zone is configured to be Dublin, i.e. IST (Irish summer time)
# in summer, UTC (in Ruby still referred to as GMT) in winter.
# When writing to the DB times will first be converted it to Irish time (if it's not already).
# When reading no conversion happens but the time zone is set as being IST/GMT.
#
# Methods such as Time.now will return the current time _in Ireland_. So if your
# machine is in CET they will be one hour earlier, but they will be correct because
# their time zone is also set to IST/GMT. And because their time zone is IST/GMT
# they will be written to the DB without conversion.
#
# One caveat : Time.utc and similar methods will return the actual UTC time, which
# is usually not what you want, so use Time.new instead.
