# DATE\$1CMP\$1TIMESTAMPTZ function
DATE\$1CMP\$1TIMESTAMPTZ compares a date to a timestamp with time zone and returns `0` if the values are identical, `1` if *date* is greater chronologically and `-1` if *timestamptz* is greater.
## Syntax
```
DATE_CMP_TIMESTAMPTZ(date, timestamptz)
```
## Arguments
*date*
A column of data type `DATE` or an expression that implicitly evaluates to a `DATE` type.
*timestamptz*
A column of data type `TIMESTAMPTZ` or an expression that implicitly evaluates to a `TIMESTAMPTZ` type.
## Return type
INTEGER
## Examples
The following example compares the date `2008-06-18` to LISTTIME. Listings made before this date return `1`; listings made after this date return `-1`.
```
select listid, '2008-06-18', CAST(listtime AS timestamptz),
date_cmp_timestamptz('2008-06-18', CAST(listtime AS timestamptz))
from listing
order by 1, 2, 3, 4
limit 10;
