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.
What is timestamp in MySQL?
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’ . 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 do you format a TIMESTAMP?

How do you add a timestamp to a value?
You can use the below code: insert into tablename (timestamp_value) values (TO_TIMESTAMP(:ts_val, ‘YYYY-MM-DD HH24:MI:SS’)); If you need the current timestamp to be inserted then use the following code: insert into tablename (timestamp_value) values (CURRENT_TIMESTAMP);
Is timestamp same as datetime?
In MySQL5+, TIMESTAMP value converts from the current time to UTC and vice-versa while DATETIME does not do any conversion. TIMESTAMPdiffers with current time zone settings while DATETIME remains constant. TIMESTAMP data can be indexed while the DATETIME data cannot.
