What is the difference between TIMESTAMP and time MySQL?
What is the difference between MySQL DATETIME and TIMESTAMP data type? Range − Datetime data type supports a date along with time in the range between 1000-01-01 00:00:00 and 9999-12-31 23:59:59. But timestamp data type supports a date along with time in the range between ‘1970-01-01 00:00:01’ to ‘2038-01-19 08:44:07’.

Is TIMESTAMP or datetime better?
TIMESTAMP is four bytes vs eight bytes for DATETIME . Timestamps are also lighter on the database and indexed faster. The DATETIME type is used when you need values that contain both date and time information. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format.
What is the difference between date time and TIMESTAMP?
Just as DATETIME , the TIMESTAMP data type contains both the date and the time in the following format YYYY-MM-DD hh:mm:ss . However, unlike DATETIME , the TIMESTAMP data type has a fixed range between 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC.
How is timestamp stored in MySQL?
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, which is stored “as is”.) By default, the current time zone for each connection is the server’s time.

Should I use Unix timestamps or datetime in MySQL?
Timestamps in MySQL are generally used to track changes to records, and are often updated every time the record is changed. If you want to store a specific value you should use a datetime field. If you meant that you want to decide between using a UNIX timestamp or a native MySQL datetime field, go with the native format.
Should I use a datetime or Timestamp field?
I recommend using neither a DATETIME or a TIMESTAMP field. If you want to represent a specific day as a whole (like a birthday), then use a DATE type, but if you’re being more specific than that, you’re probably interested in recording an actual moment as opposed to a unit of time (day,week,month,year).
How do I add a timestamp to a MySQL record?
You can do calculations within MySQL that way (“SELECT DATE_ADD (my_datetime, INTERVAL 1 DAY)”) and it is simple to change the format of the value to a UNIX timestamp (“SELECT UNIX_TIMESTAMP (my_datetime)”) when you query the record if you want to operate on it with PHP. Show activity on this post.
