+     * This method converts the "timestamp" variable into the same date format as Hypixel represents it in the museum.
+     * Currently, there are two types of string timestamps the legacy which is built like this
+     * "dd/MM/yy hh:mm" ("25/04/20 16:38") and the current which is built like this
+     * "MM/dd/yy hh:mm aa" ("12/24/20 11:08 PM"). Since Hypixel transforms the two formats into one format without
+     * taking into account of their formats, we do the same. The final result looks like this
+     * "MMMM dd, yyyy" (December 24, 2020).
+     * Since the legacy format has a 25 as "month" SimpleDateFormat converts the 25 into 2 years and 1 month and makes
+     * "25/04/20 16:38" -> "January 04, 2022" instead of "April 25, 2020".
+     * This causes the museum rank to be much worse than it should be.
+     * <p>
+     * This also handles the long timestamp format introduced in January 2024 where the timestamp is in epoch milliseconds.
