+/*************************************************************
+  Blynk is a platform with iOS and Android apps to control
+  ESP32, Arduino, Raspberry Pi and the likes over the Internet.
+  You can easily build mobile and web interfaces for any
+  projects by simply dragging and dropping widgets.

+
+ *************************************************************
+
+  Blynk can provide your device with time data, like an RTC.
+  Please note that the accuracy of this method is up to several seconds.
+
+  Datastream setup:
+    Virtual Pin V1, type: String
+    Virtual Pin V2, type: String
+
+  App dashboard setup:
+    Value Display widget on V1
+    Value Display widget on V2
+
+  NOTE: On Web dashboard, use Label widgets
+
+  WARNING:
+  For this example you'll need Time keeping library:
+    https://github.com/PaulStoffregen/Time
+
+  This code is based on an example from the Time library:
+    https://github.com/PaulStoffregen/Time/blob/master/examples/TimeSerial/TimeSerial.ino
