Absolute time does not behave as expected

[TristanBrotherton]

Description of Issue

Thank you for an excellent plugin. I have successfully connected my Bosch dishwasher, and wanted to expose a button to start a wash after midnight. Which I setup as follows:

Please note the start time of 1 minute after midnight - however this time does not seem to be honored, and the wash is set on a timer an hour and half from now. (Currently 3:30pm PST) - Is it possible this is a time zone issue? I am in California, USA.

Expected Behaviour

I expected the wash to start after midnight

I believe perhaps the absolute time is GMT.

[thoukydides]

This plugin uses whatever your server’s Node.js considers to be the local timezone. There is no explicit processing of timezones.

Check that your server is correctly configured using timedatectl. You can also set the timezone explicitly by setting the TZ environment variable.

That would be it, the server is on GMT. - Thanks for the response.
