Print time during backup

Hello,

I am running gitlab-ce-10.1.0 and I am trying to figure out a way to print the time before starting the backup of repository. The main idea is to have a record of how long does it take to back up a repository.

Currently the output looks like this:

Dumping database ... 
Dumping PostgreSQL database gitlabhq_production ... [DONE]
done
Dumping repositories ...
 * department/project1 ... [DONE]
 * department/project1.wiki ...  [SKIPPED]

List item

I want to have output like this:

Dumping database ...
02.12.2017 20:03:00 
Dumping PostgreSQL database gitlabhq_production ... [DONE]
02.12.2017 20:03:10 
done
Dumping repositories ...
02.12.2017 20:03:11 
 * department/project1 ... [DONE]
02.12.2017 20:03:20
 * department/project1.wiki ...  [SKIPPED]
02.12.2017 20:03:11 

I found the code in /opt/gitlab/embedded/service/gitlab-rails/lib/backup/repository.rb but I am not experienced in Ruby, so before googling “how to print local time in Ruby”, has anyone done this or similar change and can give me a hint how to do it?

Thanks in advance.
