MongoDB Show Timezone Command

MongoDB is a popular NoSQL database that allows developers to store and manage unstructured data. One important aspect of working with MongoDB is understanding time zones. MongoDB allows you to store dates with time zones, and provides commands for working with them. In this article, we will cover the "show timezone" command.

Syntax

The "show timezone" command can be used in the MongoDB shell to display the current time zone.

> show timezone

This command will return the current time zone in the following format:

{"offset" : "<timezone_offset>", "isDst" : <true|false>, "name" : "<timezone_name>"}

Description

The "show timezone" command is used to display the current time zone in MongoDB. This is useful when working with dates and times, as it allows you to ensure that your data is stored and retrieved correctly based on the appropriate time zone.

The output of this command provides the following information:

• offset: The difference in hours and minutes between the local time and Coordinated Universal Time (UTC).
• isDst: Whether or not the current time zone is observing daylight saving time.
• name: The name of the current time zone.

Example

Let's see an example of how to use the "show timezone" command.

> show timezone
{"offset" : "+08:00", "isDst" : false, "name" : "Asia/Shanghai"}

In this example, the command returns that the current time zone is "Asia/Shanghai", with a UTC offset of "+08:00" and not observing daylight saving time.

Conclusion

The "show timezone" command is a useful tool for developers who work with dates and times in MongoDB. By understanding how to use this command, you can ensure that your data is stored and retrieved correctly based on the appropriate time zone.
