Time format in SQL Server
The date type is a new data type introduced in SQL Server 2008. It only contains the date without the decimal part. The date range that can be represented is from January 1, 0001 to December 31, 9999. It requires 3 bytes of storage space.
datetime contains the date and time, and the range that can be expressed is from 00:00:00 on January 1, 1753 to 23:59:59:997 on December 31, 9999. The precision is 3.33 milliseconds, which occupies 8 bytes. The default time is 1900- 01-01 00:00:00

Let me add the date type of oracle
Date type The format of date type storage data is year, month, day, hour, minute and second, which can be accurate to the second
The format of timestamp type storage data is year, month, day, hour, minute and second, which can be accurate to nanoseconds (9 digits)
Date type data can be displayed up to year, month, day, or year, month, day, hour, minute, and second, depending on the accuracy of the stored data
There is no datetime type in oracle
