+
+In addition to the Date and Time kit, the Timestamp now also supports the 'unstyled' variant! The days of not having styled options for Date/Time kits are over. The new & improved Timestamp kit is now more flexible than ever with the ability to customize font sizes, weight, and color by wrapping the kit in any of our typography kits!
