no, that is incorrect... that's not "according to him"... that's a defect in the program from using too small a variable type to store the number of seconds in... effectively what you are seeing is modulo arithmetic also known
as rollover where the counter rolls over to the lowest end of the range when the value exceeds the maximum value...

|===================================================================|
|Type      Range                                       Size in bytes|
|===================================================================|
|Byte                         0 .. 255                             1|
|Shortint                  -128 .. 127                             1|
|Smallint                -32768 .. 32767                           2|
|Word                         0 .. 65535                           2|
|Integer            either smallint or longint           size 2 or 4|
|Cardinal                    longword                              4|
|Longint            -2147483648 .. 2147483647                      4|
|Longword                     0 .. 4294967295                      4|
|Int64     -9223372036854775808 .. 9223372036854775807             8|
|QWord                        0 .. 18446744073709551615            8|
|===================================================================|

back when the program was written Longword, Int64, and QWord likely did not exist... Byte and Word were the only numerical entities with no negative capabilities...

in short, it is simply numeric rollover due to using too small a variable type for the number being stored...
