pisdk php when get values use ArcValue

Question

When I use $point->Data()->ArcValue(strtotime("now"),rtAuto,null); I get below error:

Fatal error: Uncaught com_exception:
Parameter 0: Type mismatch.in C:\index3.php:58 Stack trace: #0 C:\index3.php(58): variant->ArcValue(1625754415, 5, NULL) #1 {main}thrown in C:\index3.php on line 58

How can I use the function ArcValue?

Answer 1

Seems like the time stamp is wrong.
