Ruby: now.strftime(“%a, %d %b %Y %X %z”) gives wrong time

Question

Hello guys I'm using a Ruby script to send error mails ( https://github.com/u-ichi/fluent-plugin-mail/blob/master/lib/fluent/plugin/out_mail.rb ) which relies on Net::SMTP. The time is obtained using "Time::now.strftime("%a, %d %b %Y %X %z")",

...
smtp.send_mail(<<EOS, @from, @to.split(/,/), @cc.split(/,/), @bcc.split(/,/))
   Date: #{Time::now.strftime("%a, %d %b %Y %X %z")}
   From: #{@from}
   To: #{@to}
   Cc: #{@cc}
   Bcc: #{@bcc}
   Subject: #{subject}
   Mime-Version: 1.0
   Content-Type: text/plain; charset=utf-8
   #{body}
EOS
smtp.finish

Unfortunately, I'm getting the mails with a wrong time. I don't know how Time::now.strftime works but I guess they pick the time from the server? I'm on CentOS and checked the "date" of the server and found no error...

Is there other way to get the time?

Answer 1

You should convert this time in a specific timezone. like:

time_zone = ActiveSupport::TimeZone.new(your_desire_time_zone)
converted_time = time.in_time_zone(time_zone)

or convert in UTC

converted_time = Time.now.utc

Then try to use strftime

converted_time.strftime("%a, %d %b %Y %X %z")
