title: Remove the days in Timedelta column
body: <p>This is a column in my data frame and I want to remove the 0 days so the column will just show the time</p>
  <pre><code>           Time
  0     0 days 04:00:00
  1     0 days 04:01:00
  2     0 days 04:03:00
  3     0 days 04:04:00
  4     0 days 04:07:00
  </code></pre>
  <p>Desired output:</p>
  <pre><code>         Time
  0      04:00:00
  1      04:01:00
  2      04:03:00
  3      04:04:00
  4      04:07:00
  </code></pre>
  <p>I've been recommended this question &gt; <a href="https://stackoverflow.com/questions/53129971/remove-the-days-in-the-timedelta-object/53130019#53130019">Link</a></p>
  <p>And tried to suit it to my code with this code:</p>
  <pre><code>df['Time'] = df['Time'] - pd.to_timedelta(df['Time'].dt.days, unit='d')
  </code></pre>
  <p>But I'm still getting the same output:</p>
  <pre><code>           Time
  0     0 days 04:00:00
  1     0 days 04:01:00
  2     0 days 04:03:00
  3     0 days 04:04:00
  4     0 days 04:07:00
  </code></pre>
