How does SQL store time in database?
SQL Server actually stores time as fractions of a day. For example, 1 whole day = value of 1. 12 hours is a value of 0.5. If you want to store the time value without utilizing a DATETIME type, storing the time in a decimal form would suit that need, while also making conversion to a DATETIME simple.
Is date a data type?
The DATE data type stores the calendar date. … Because DATE values are stored as integers, you can use them in arithmetic expressions. For example, you can subtract a DATE value from another DATE value. The result, a positive or negative INTEGER value, indicates the number of days that elapsed between the two dates.
How are dates stored in database?

Alternatively, you can pick a ‘datetime’ column-type, as long as that type ignores timezones altogether.
