Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ESP8266 NTP/RTC Clock with temp
I believe this is the ntp lib I'm currently using... https://github.com/arduino-libraries/NTPClient

How do you get time; is there a good library ;
Normally you sync the clock one or two times per day from the NTP server. Then you calculate the time from the time passed since last sync. If you are using the arduino ecosystem you can use this library. Otherwise you have to implement the NTP client and a timer based on interrupts.

Two databases in IOT solution
I used This ntp library to insert accurate datetime for my recent ESP32 project. Super easy API, with support for each time zone. Not realistic if you already have a large program overhead.

By "NTP", you mean you used this library? Did you call the update() function in the loop()?

How to setup a Real Time Clock over the internet that can be used by esp?
You can use the NTP library with the time library from Paul Stoffregen.

ESPDateTime -Github is the easiest one I have found.
What are some alternatives?
When comparing NTPClient and ESPDateTime you can also consider the following projects:
