Ah, I should not have quoted the line array=("${array_val}")
Try is with array=(${array_val}) for the last line instead. Does that help?
You might need to work with line 6 too, perhaps this would be better overall:-
The date/time value is in seconds from the Epoch, else the array would split up. is that a problem? We can work on fixing it if we need to.

array_reduce
ARRAY_REDUCE(3) 1 ARRAY_REDUCE(3)array_reduce - Iteratively reduce the array to a single value using a callback functionSYNOPSIS
mixed array_reduce NULL (array $array, callable $callback, [mixed $initial])
DESCRIPTION array_reduce(3) applies iteratively the $callback function to the elements of the $array, so as to reduce the array to a single value.
PARAMETERS
o $array
- The input array.
o $callback
-
mixed callback (mixed $carry, mixed $item)
o $carry
- Holds the return value of the previous iteration; in the case of the first iteration it instead holds the value of $ini-
tial.
o $item
- Holds the value of the current iteration.
o $initial
- If the optional $initial is available, it will be used at the beginning of the process, or as a final result in case the array
is empty.
RETURN VALUES
Returns the resulting value.
If the array is empty and $initial is not passed, array_reduce(3) returns NULL.
