Best way to generate a migration timestamp

Question

I am trying to generate a timestamp for rails migration that I am copying into my app from an engine as part of rake task.

The following works fine, but since rails already does the same thing, i didn't know if there is a better way to do this?

Time.now.to_s.split(" ")[0..1].join(" ").gsub!(/\D/, "")

Answer 1

@timestamp = Time.now.strftime("%Y%m%d%H%M%S")

Answer 2

Time.now.utc.strftime("%Y%m%d%H%M%S")
