Find and Replace with Regex

Regex to find date and time.

Option 1: ([\d]{1,2})/([\d]{1,2})/([\d]{4}) in format mm/dd/yyyy

Option 2: [0-9]{4}-[0-9]{2}-[0-9]{2}T in format yyyy-mm-dd

Option 3: ([0-1]?[0-9]|2[0-3]):[0-5][0-9] in format HH:mm

In Sublime Text Find and Replace (CMD+OPT+F) replace with $3-$1-$2

This replaces date mm/dd/yyyy with yyyy-mm-dd
