I know it's :nail_care:, but what about:

```ruby
  time_split = pieces[1].split(':')
  time = "#{time_split.first}:#{time_split[1]}:\\d{2}"
```

If you want to kill me for being so annoying, I understand you. :kissing_heart: 

PS.: The kiss was a joke, don't understand it wrong. :laughing:
