This article contains examples of converting a time value to a datetimeoffset value in SQL Server using Transact-SQL.
When you convert a time value to datetimeoffset, the date is set to ‘1900-01-01’ and the time is copied. A time zone offset is added and set to +00:00.
This article contains examples of converting a smalldatetime value to a datetime value in SQL Server.
When you convert a smalldatetime value to datetime, the hours and minutes are copied, and the seconds and fractional seconds are set to 0.

When you convert a time value to datetime, extra information is added to the value. This is because the datetime data type contains both date and time information. The time data type, on the other hand, only contains time information. Therefore, date information is added to the value when you perform such a conversion. Specifically, the date is set to ‘1900-01-01’.

When you convert a date value to datetimeoffset, extra information is added to the value. This is because the datetimeoffset data type contains both date and time information, as well as the time offset information. In other words, the datetimeoffset data type defines a date that is combined with a time of a day that has time zone awareness and is based on a 24-hour clock. The date data type, on the other hand, only contains date information.
When we convert from date to datetimeoffset, the time (and time zone offset) is automatically added to the value. However, you can always change the value if required (including the time zone offset).
The datetimeoffset data type also allows you to specify the fractional seconds precision. If you don’t specify this, it uses a scale of 7. This means it will include 7 digits on the right side of the decimal point.
This article contains examples of converting a date value to a smalldatetime value in SQL Server.
When you convert a date value to smalldatetime, extra information is added to the value. This is because the smalldatetime data type contains both date and time information. The date data type, on the other hand, only contains date information.
However, there are cases where a date to smalldatetime conversion might fail. In particular, if the date value is outside the range supported by smalldatetime then it will fail with an error.
In any case, below are examples of converting between these two data types.
This article contains examples of converting a date value to a datetime2 value in SQL Server.
When you convert a date value to datetime2, extra information is added to the value. This is because the datetime2 data type contains both date and time information. The date data type, on the other hand, only contains date information.
The datetime2 data type is basically an extension of the datetime data type. It has a larger date range, a larger default fractional precision, and optional user-specified precision.
In any case, the conversion process is exactly the same regardless of the data type. The only difference is the amount of information that’s available between date, datetime and datetime2.

When you convert a date value to datetime, extra information is added to the value. This is because the datetime data type contains both date and time information. The date data type, on the other hand, only contains date information.
In MySQL, the TO_SECONDS() function returns the number of seconds since the year 0.
This function is not to be confused with the TIME_TO_SECONDS() function, which returns the number of seconds in a given time value provided as an argument.
When using MySQL, you can use the TIME_TO_SEC() function to return the number of seconds in a time value. Specifically, this function returns the time argument, converted to seconds.
This function is not to be confused with the TO_SECONDS() function, which, given a date or datetime argument, returns the number of seconds since year 0.
Here’s how TIME_TO_SEC() works.
