Puerto Rico does not observe Daylight Saving Time (DST). No matter how lucky we are that we don’t have to observe this “fake time” (as my mom calls it). It is still confusing for Puerto Ricans because unfortunately everything Puerto Rico does revolves around the US. The problem is we have to convert the times. So if I have a regular appointment at 10am, it is now changed to 11am. To give some examples - So the time changes for our regular conference calls at work. TV time change to fit your times. My clock that magically receives it time somehow through the air will be off by an hour. The list can could go on for ever.
