Why would a FindEq function would return me a "false" timestamp?

Hi,

      I'm a new user of PI System and i'd like to understand why when i use a FindEq function to find the timestamp of an       archive point, the result that's been giving me ain't accurate.

 

      For example, i use this formula: FindEq('Recette_Numero', '-1000dt', '*', 1021503) 

                             where Recette_Numero is a tag name referring to the number of a recipe that is being archive.

  

      When i evaluate that formula, the timestamp that is being return to me is 2020/09/03 15:07:20.

 

      However, there is no such archive at that timestamp.

                              

 

      Can someone help me with this? Thanks in advance.
