Add the example script to your app and run it. Then add, at least, the fields listed in the results column to a sheet in your app to see the result.

This example checks if an invoice date falls at any time in the day starting with the base_timestamp.

TempTable:

LOAD RecNo() as InvID, * Inline [

InvTime

28/03/2012

10/12/2012

5/2/2013

31/3/2013

19/5/2013

15/9/2013

2/3/2014

14/5/2014

13/6/2014

7/7/2014

4/8/2014

];

InvoiceData:

LOAD *,

InDay(InvTime, '28/03/2012 00:00:00', 0) AS InDayEx

Resident TempTable;

Drop table TempTable;

The resulting table contains the original dates and a column with the return value of the inday() function.
