Can I use this library also without Internet connection? about eztime

Yes you can... Simply point it to the local NTP server and do not use .setLocation. (That would try to connect to my timezone info server.)

That means you need to feed it timezone information, either as a static offset to UTC or as a 'Posix' string that has information about when to switch from Standard to Daylight Savings Time. Use the .setPosix method. (User Manual)

You can also use ezTime without any network at all, for instance if you have a time source that is not NTP, such as a hardware RTC device or a GPS receiver. In that case use setInterval() to turn off NTP updating and use .setTime (User Manual) to set/update the time yourself. Or, if you are on a memory constrained platform such as AVR Arduinos, do not even compile networking support into ezTime altogether by commenting out #define EZTIME_NETWORK_ENABLE in ezTime.h in the library's src directory. (User Manual)
