Mysql Utc Datetime

UTCTIMESTAMP function. In MySQL, the UTCTIMESTAMP returns the current UTC date and time as a value in 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS.uuuuuu format depending on the usage of the function i.e. In a string or numeric context. Note: Since UTCTIMESTAMP works on current datetime, your output may vary from the output shown. When you query a TIMESTAMP value, MySQL converts the UTC value back to your connection’s time zone. Note that this conversion does not take place for other temporal data types such as DATETIME. By default, the connection time zone is the MySQL Server’s time zone. And you can use a different time zone when you connect to MySQL Server. From The DATE, DATETIME, and TIMESTAMP Types: MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. – ypercubeᵀᴹ Jul 1 '12 at 12:05. The DATETIME value is the local time of the server running MySQL in whatever time zone that is. If all you are ever doing only concerns one server in one time zone, DATETIME will probably fit most.

DATETIME and TIMESTAMP

Some MySQL data types are a bit confusing at first sight. Without reading through the documentation (and sometimes even after reading it), it’s hard to figure out which data type is the right one for your current needs. That’s why we’re here.

So you need to store date and time pieces of information, but wondering which data type you should use in MySQL - DATETIME or TIMESTAMP? The answer is - it depends on your needs.

First, let’s look into the MySQL official documentation to see what MySQL has to say about both of them and then we’ll look into practical uses for each of them.

DATETIME - “The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.

TIMESTAMP - “The TIMESTAMP data type is used for values that contain both date and time parts. TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC.”

How are they different?

Well, I’m glad I read the documentation mentioned abvove, because they look, hmmm, the same. But, if you keep reading that documentation page, you’ll eventually reach this part:

War thunder ipm1. “MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such as DATETIME.)”.

So how does this impact your implementation and whether to choose DATETIME or TIMESTAMP as your data type?

Mysql Utc Timestamp To Datetime

Well, as mentioned above, when using the TIMESTAMP data type, the values are converted by the database to UTC (universal time zone) and are stored in that timezone. This means that when you fetch (SELECT) this data, a conversion will be done from UTC to the current time zone, and only then the data will be returned. This behavior doesn’t occur for DATETIME stored values.

Practical uses

Well, if you are serving customers in different countries with different application instances, by using TIMESTAMP, you’ll be able to serve the same date and time data in different timezones, directly from the database.

Please note that by default the applied timezone is the server’s timezone. You can set the timezone on a per connection basis if you wish to change it. For example, SET time_zone = '-8:00'; .

To summarize, if you want to serve your date and time data the same way regardless of timezones, you can use the DATETIME type (which will also allow you to use all the date & type functions built in MySQL). Otherwise, you can use TIMESTAMP and serve the data on a per-timezone basis.
