title: Extract time from timestamp?
body: <p>Essentially, I want only the hour, minute, and seconds from a column of timestamps I have in R, because I want to view how often different data points occur throughout different times of day and day and date is irrelevant.</p>
  
  <p>However, this is how the timestamps are structured in the dataset: 
  2008-08-07T17:07:36Z</p>
  
  <p>And I'm unsure how to only get that time from this timestamp.</p>
  
  <p>Thank you for any help you can provide and please just let me know if I can provide more information!</p>
