implementing dynamic variable

[Frank Fock]

Hi Mauro,

The problem is that your object is of type OctetString, but
you are trying to assign a TimeTicks value to it. I wonder
why the agent does not crash?

You should convert the TimeTicks value to a string with
*((OctetStr*)value) = TimeTicks(get()).get_printable();

Regards,
Frank
