Thanks for the reply, it is an intouch.2 WiFi Spa controller by Gecko Alliance and I have been discussing this with their technical support and have been advised:

1. The device uses the Router Only.

2. A NTP Server / Timezone can't be set.

3. I have confirmed in the App, that there are no settings available to set the "Time Source" and "Timezone".

I asked the question to their technical support "Is it possible to set an NTP Server and Time Zone, in the application in a future release? " and the response was "No because the unit pulls the time from the router it is connected to". I find it very hard to believe that in 2025 you would hard code the NTP source, presumable to the device you are getting a DHCP address from.

So hence question around can the Deco acts an NTP Server, and the other question, I have is when I do a lookup of time in the Deco App. It seems to take a few seconds to get the time/timezone information, so is the time stored in the Deco Devices or is it getting the time information from the Internet when required?

I have to say that coming from other devices, the limited access to a full-blown interface in the Deco's is a little strange, don't get me wrong they work and are easy to setup, but not being able to see how it gets it time, is also a little frustrating.
