### Is your feature request related to a problem or challenge?
I’d like to ask if there is a way to get a result similar to `datediff`
function , also it seems that this function is not available in DataFusion.
i try another way like this,but how can i get 6 days from interval result
```
select to_timestamp(now())-to_timestamp('2023-07-20T05:44:00.419557');
+------------------------------------------------------------------------+
| to_timestamp(now()) - to_timestamp(Utf8("2023-07-20T05:44:00.419557")) |
+------------------------------------------------------------------------+
| 0 years 0 mons 6 days 0 hours 51 mins 7.343851000 secs |
+------------------------------------------------------------------------+
```
### Describe the solution you'd like
something like `date_diff`
### Describe alternatives you've considered
add udf like `date_diff`
or
make
`select extract(day from interval '1 days' ); `
work
```
Error during planning: No function matches the given name and argument types
'date_part(Utf8, Interval(MonthDayNano))'. You might need to add explicit type
casts.
Candidate functions:
date_part(Utf8, Date32)
date_part(Utf8, Date64)
date_part(Utf8, Timestamp(Second, None))
date_part(Utf8, Timestamp(Microsecond, None))
date_part(Utf8, Timestamp(Millisecond, None))
date_part(Utf8, Timestamp(Nanosecond, None))
date_part(Utf8, Timestamp(Nanosecond, Some("+00:00")))
```
