"Error Constructing DateTime: Value not valid date string" on "%z" format specifier (time zone)

[sastanin]

I noticed that string-based DateTime constructor with "%z" in the format specifier throws an exception:

Code to reproduce this issue:

// exception: Error Constructing DateTime: Value not valid date string.
return DateTime("24/07/2025 08:01:47 +0200", "%d/%m/%Y %H:%M:%S %z").toString("%F %T %z");

FlexSim 25.2.0 Beta build 94 and earlier versions.

The specifier works correctly in the DateTime.toString method.
