> ## DATETIME function

> Converts date and time values, or a character string, into a DATETIME.

> Note: If any argument is the Unknown value (`?`), the result is the Unknown value (`?`).

> #### Syntax

>     DATETIME (date-exp [, mtime-exp ] )

>     DATETIME ( string )

>     DATETIME (month, day, year, hours, minutes [, seconds [, milliseconds ] ] )

> ``date-exp``

> An expression whose value is a DATE.

> ``mtime-exp``

> An expression whose value is an integer representing the number of milliseconds since midnight.

> ``string``

> A character expression whose value is a string containing a DATETIME. The date portion of the string must have the format specified by the DATE-FORMAT attribute. The time portion must be in a valid time format (HH:MM:SS, and so on).

> ``month``

> An expression whose value is an integer from 1 to 12, inclusive.

> ``day``

> An expression whose value is an integer from 1 to the highest valid day of the month.

> ``year``

> An expression that evaluates to a year.

> ``hours``

> An expression whose value is an integer from 0 to 23, inclusive.

> ``minutes``

> An expression whose value is an integer from 0 to 59, inclusive.

> ``seconds``

> An expression whose value is an integer from 0 to 61, inclusive. The upper limit is 61 for leap seconds.

> ``milliseconds``

> An expression whose value is an integer from 0 to 999, inclusive.

> Example

> Following is an example of using the DATETIME function:

>     DEF VAR my-datetime as DATETIME.

>     my-datetime = DATETIME(TODAY, MTIME).
>     /* The statement above is equivalent to "my-datetime = NOW". */

> The following statements result in the same DATETIME value:

>     my-datetime = DATETIME(5, 5, 2002, 7, 15, 3).
>     my-datetime = DATETIME(“05-05-2002 07:15:03”).
