Date functions perform an operation on a date and time input value and return a string, numeric, or date and time value.
The following information describes the functions available for building expressions.
Tip:
- Any information within square brackets [ ] is optional.
- For more information on formatting strings, see Conversion Functions.
- If you want the current date/time associated with the UTC time zone, use the format CurrentDateTime("UTC").
DATE
- Description
- Returns a date value representing a specified year, month, day, hour, minute, or second. The default value for date/time is always associated with the current time zone, unless a time zone is specified using a different function in the expression. Any actions performed in the same expression using this resultant value uses the current or specified time zone for evaluation.
Note: If this function is used as the return value of an expression, the DateTime will be in universal time (UTC).
- Format
- DATE(int_year, int_month, int_day, [, int_hour, int_minute, int_second], [, timezone]])
| Parameters | Required? | Data Type | Description |
|---|
| int_year | Yes | Numeric | Integer for the year field of the date. |
| int_month | Yes | Numeric | Integer for the month field of the date. |
| int_day | Yes | Numeric | Integer for the day field of the date. |
| int_hour | No | Numeric | Integer for the hour field of the date. |
| int_minute | No | Numeric | Integer for the minute field of the date. |
| int_second | No | Numeric | Integer for the second field of the date. |
| timezone | No | String | Abbreviation of the time zone of the date. |
- Example
- DATE(2008,10,31,11,59,59)
- DATE(2008,10,31)
- DATE(2008,10,31,11,59,59,"MST")
CurrentDateTime
- Description
- Returns the current date and time. The default value for date/time is always associated with the current time zone, unless a time zone is specified using a different function in the expression. Any actions performed in the same expression using this resultant value uses the current or specified time zone for evaluation.
To work with UTC values, you can use the UTC time zone. You can do this by specifying it in a DateTime function, or by converting the DateTime value to the UTC time zone. For example, the DateTime function can be expressed as CurrentDateTime("UTC") or as ConvertTimeZone({dateTimeVariable}, "UTC".
Note: If this function is used as the return value of an expression, the DateTime will be in universal time (UTC).
- Format
- CurrentDateTime([timezone])
| Parameters | Required? | Data Type | Description |
|---|
| timezone | No | String | Time zone to get the current date and time from. |
DateTimeCompare
- Description
- Compares two Date-Time values and returns an indication of their relative values; that is, an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.
- Format
- DateTimeCompare(dateTime1, dateTime2)
| Parameters | Required? | Data Type | Description |
|---|
| dateTime1 | Yes | DateTime | First date and time value to compare. |
| dateTime2 | Yes | DateTime | Second date and time value to compare. |
- Example
- DateTimeCompare(DATE(1899,10,31,11,59,59) , DATE(1999,10,31,11,59,59) ) < 0
- DateTimeCompare(DATE(1999,10,31,11,59,59) , DATE(1999,10,31,11,59,59) ) = 0
- DateTimeCompare(DATE(1999,10,31,11,59,59) , DATE(1899,10,31,11,59,59) ) > 0
Today
- Description
- Returns the current date as a date and time value. The default value for date/time is always associated with the current time zone, unless a time zone is specified using a different function in the expression. Any actions performed in the same expression using this resultant value uses the current or specified time zone for evaluation. The time part of the day is zero (midnight).
Note: If this function is used as the return value of an expression, the DateTime will be in universal time (UTC).

ConvertTimeZone
- Description
- Changes the time zone associated with a DateTime value. This function does not change the specific time being referenced; that is, the universal (UTC) time remains the same. A DateTime value that is associated with the time zone is returned.

|---|
| date | Yes | DateTime | Date and time to associate with a timezone. |
