Date Stamp

in game time only counts when the server is running and it is based on your set gametimespeed in the server.properties file

To get the real world time you need to use java default methods for example https://docs.oracle.com/javase…s/api/java/util/Date.html or https://docs.oracle.com/javase…/java/time/LocalDate.html

As @Minotorious said, the ingame time only increments while the server is running. The server can configure the time speed. This value is persistent, so you can only reset it manually or by creating a new world

If you just want to get the real time timestamp, it's better to use use the Java function System.currentTimeMillis();, this returns a millisecond timestamp (i.e. milliseconds passed since 1 January 1970 UTC). If you need a unix timestamp (seconds instead of milliseconds), you can just divide this value by 1000, e.g.:

long timestamp = System.currentTimeMillis() / 1000;


//If you need an integer instead, just cast it:
int timestamp = (int)(System.currentTimeMillis() / 1000);

as stated in red's post above the start of the millisecond date is the 1st January 1970 UTC.

To get the current time out of a millisecond timestamp you can use the Date() java class: https://docs.oracle.com/javase…s/api/java/util/Date.html

This method:
Date(long date)
Allocates a Date object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.

GMT (Greenwich Mean Time) does not support daylight saving, it is just like UTC (Coordinated Universal Time), a standard time zone not changing no matter what.

You are probably confusing it with either CET (Central European Time) that changes to CEST (Central European Summer Time), or BST which is the British Summer Time timezone used in the UK in the summer in place of the GMT one as the latter doesn't support daylight saving.

It is central time US that makes the problem.

oh ok well then I would recommend either converting all values to a specific timezone or using the LocalDateTime Java class to use the time of the server in the timezone the server is in
