Timestamp in specific time error

I am trying to send a signal in hour I want every day but if I put 14:30 it sends at 16:30, and if I put it 12:30 it sends at 14:30. How can I correct that?

Check the time zone settings on your server

I can´t find the setting of Node-Red to change the time zone settings...

Node-RED takes the time settings from the server that it runs on.

the server is running on the right time.

What OS are you running the server on?
