I am using Raspberry Pi 4 as a gateway to my esp8266 devices. I have connected ethernet to Raspberry Pi for internet connection. It works fine. I want to generate NTP time in my ESP8266 device.

When I connect the devices to direct Wi-Fi they are getting right time. But when I connect them to Raspberry Pi gateway they are getting date 01.01.1970 .

How to get current date from Raspberry Pi gateway?

Recent Raspberry Pi OS includes systemd-timesyncd as the NTP client. Unfortunately for you, systemd-timesyncd does not implement the server functionality, so it cannot provide network time to clients downstream.

You'll have to set up a full-featured NTP server such as ntp, openntpd or chrony (you may disable systemd-timesyncd, but you don't have to: it is polite enough not to interfere). Or, if you have any of these set up already, you need to configure them to act as a server.
