Time.is automatically displays the time in your time zone by using your IP address to detect your location. Your IP address is 126.96.36.199. Your detected location is New York, United States. The time-zone offset is the difference, in minutes, from local time to UTC. Note that this means that the offset is positive if the local timezone is behind UTC, and negative if it is ahead. For example, for time zone UTC+10:00 (Australian Eastern Standard Time, Vladivostok Time, Chamorro Standard Time), -600 will be returned. UTC current time is 07:10:17. UTC current date is 3rd Monday May 2021. UTC: Coordinated Universal Time. Jul 21, 1983 The getUTCDate method returns the day of the month (from 1 to 31) of the date object, according to universal time. The UTC methods calculate their date assuming that the date object is of local time and date. Tip: The Universal Coordinated Time (UTC) is the time set by the World Time Standard. Note: UTC time is the same as GMT time.
One of the key questions developers have in every programming language is the one related to time and timezones. Before we try to answer how you can get the current date and time in UTC or GMT in Java, there are a few concepts you need to understand.
To begin with, GMT (which stands for Greenwich Mean Time) is not the same as UTC (which stands for Coordinated Universal Time): Dreamweaver xampp testing servers.
- GMT is a time zone used in some but not all parts of the world (mainly Europe and Africa). It uses either a 24-hour format or a 12-hour format for display and its based on astronomical observations.
- UTC is not a time zone. It is a standard which we can use to display time zones. It is more stable as it takes time from an atomic clock.
If you are using the java.util.date package to get the current date and time in Java (as it looks more intuitive), you will find out soon it’s very limited. There are several reasons for that:
- It doesn’t have a time zone.
- It doesn’t represent a date. It represents an instance in time in milliseconds since the Unix epoch (1970).
Therefore, if you want to get swiftly the current time in milliseconds only, you can use the following code:

Other than that, you can also change the current system TimeZone, and if you wanted to use a different timezone, you could do it like this:
However, if you run this code, you will see the following output:
In general, this is not ideal, as it prints the current time based on the timezone of the specified region, which may be different than GMT, therefore, it should be avoided.
A better and more modern option bundled within the Java Core library (and not using any third-party offerings)is to use the java.time package.
If you look at the documentation page, the package is based on the ISO calendar system and offers a simplified API for displaying and handling date and time instances. Bellow is the depicted table of the capabilities exposed in this package:
Based on this, we can infer that this package represents the time (with the location unspecified), as UTC, or as an offset from UTC.
Indeed, if we check the Instant class to get the current time, we can see the date time printed as UTC:
This will display:
Which is the current date-time in UTC. The ending Z character denotes the Zone Offset which is Zero.
A more robust option is to convert this Instance to a ZonedDateTime as you would like to configure the current TimeZone. You can do that by using the ofInstant static factory method passing a ZoneId:
In most cases you should be using UTC format as they are mostly supported in Java.
How do I set the default locale for my JVM?
First of all, to understand how to set the default locale, you need to know what locale is. Locales identify a specific language and geographic region. They are represented as strings using the following format:
For example, here are some Locale strings:
If you run a UNIX platform (Mac, Linux), there is a convention to set some environmental variables using the LC_* prefix. For example, by running this command in the console, we can see the default system locale is en_IE:
In Java, if we call the Locale.getDefault() in a method and run the java command without any flags, it will not pick up the system Locale as specified in the LC_* variables. For example, given the following main class, located in com/thdespou/Main.java:
Now, if we change the LC_* variables to en_UK, it will still print en_IE.

In fact, looking at the Locale documentation page, there is no information on how to change that. However, by inspecting the source code of the Locale.class and particularly the static initializer block …
… and looking at the initDefault() method, we get a hint of what we exactly need to do in order to set the default locale in the JVM:
So using the following system properties:
user.language: For setting the current language
user.region: For setting the language region
Given that information, we can check in the command line for setting the default locale and using this guide. For example:
Note that this is based on this implementation of the JVM, and we should not be if this would change in the future, as it is not clearly documented in the JavaDocs.
