Help me to show time in my app
How do I set my app GMT time?
Get current date

por que es tan grande la extension


Hola @Andres_Cotes

  • Como ves, la extensión ocupa unos 400 KB, debido a que contiene una librería bastante grande.

  • Si quieres una versión reducida en tamaño de esta extensión que solo ocupa 6 KB, puedes bajar la siguiente, que solo contiene el bloque de TimeZone:
    com.KIO4_TimeZ.aix (6.0 KB)


muchas gracias Juan Por tu aporte


suppose , i using a button for waiting 15 minutes.When button click, time counting start.
Then if anyone increase system time, they need to wait 15 minutes?
can anyone hack timezone?


just lookup UTC time from the server…

Do you have a solution?

thx u for extension!


Please make in english language


hello your extension converts the time perfectly but I can’t compile apk because it goes wrong. How do I solve it? thank you


you might want to elaborate… any error message?



as we can see, you get the DX execution failed error while building the app
are you saying, the app builds fine if you remove that extension?
if yes, it might be, that the exension is not compatible with Thunkable


yes indeed it is really so. I removed the extension and used onlinechecker, to capture the exact time to launch onsignal push notification. at the times I need . thanks for the explanation


Can you make it possible??? Pls sir reply me.
