ruby - Weird Behaviors of datetime(timezone) in Rails application -

in our rails 3.2 application, have configured,

config.time_zone = 'london' config.active_record.default_timezone = :local

and in postgresql configured timezone "europe/london".

for past 1 week, our application datetime field not working timezone.

for example, if create reminder start_date @ 2015-08-18 10am. creates `2015-08-18 10:00:00 in postgres database.

when displaying in template,

reminder start date: 2015-08-18 10am (2015-08-18 10:00:00 +0100 )

but,(not always) showing utc time.

reminder start date: 2015-08-18 9am (2015-08-18 09:00:00 utc )

it not reproduced in development.

if restart unicorn server not occurring 4 hours.

anyone faced kind of problem?

i fixed issue, adding around filter in applicationcontroller.

around_filter :use_time_zone  private  def use_time_zone(&block)   time.use_zone('london', &block) end

so, whenever default timezone changed utc, override , set bst.
