title: Parsing failure when working with the rethomics (circadian behavior) package in R
body: <p>I am having issues both with my data and the test data provided in the rethomics tutorial (<a href="https://rethomics.github.io/damr.html#linking" rel="nofollow noreferrer">https://rethomics.github.io/damr.html#linking</a>) specifically at the linking step. When run the following code, it provides me with the following error.</p>
  <p>Code:</p>
  <pre><code>list.files(DATA_DIR, pattern= &quot;*.txt|*.csv&quot;)
  setwd(DATA_DIR)
  
  metadata &lt;- link_dam_metadata(metadata, result_dir = DATA_DIR)
  metadata
  </code></pre>
  <p>Output:</p>
  <pre><code>row col   expected        actual
    1  -- date like  7/1/2017 8:00
  
  Error: 1 parsing failure
  </code></pre>
  <p>I also received a similar error when attempting to apply my own data. This is coming directly from the tutorial, so is there something wrong with the code tutorial or is it something that I have not done correctly. Thank you in advance.</p>
