Thanks for the replies.
As the project currently is, there is continuous internet access, and the time is updated constantly, and it works fine!
If I give the clock as a gift to somebody else, my sister who stays at a University res, I need to know the SSID and the password, and due to internet security at University, they change the password very often. This leads to the clock either to stand still, or if it has a RTC standby, it will continue running until the time eventually goes out of synch with the real time.
Therefore, the need to update the time from a mobile phone (android) to kick the clock in synch every now and then. Because the clock only display hours and minutes, it requires update every few months!
That is why I wondered if Blynk can do this.
Is there any other app, that you suggest I try to achieve this - if Blynk as suggested by PeteKnight, can’t do this.
Thanks for the info thus far.
