VBA get time zone from weather file

Having retrieved a 'p_data' object from a weather file, I get an invalid number instead of an integer like -7 or -8 when I use the code:

sscvb_data_get_number p_data, "ts_shift_hours", dTimeZoneOffset ' Get UTC time zone offset in hours

In VBA's Immediate window:

?dTimeZoneOffset
 1.06387313834624E-311 

Can someone tell me where I have erred?

Hi Steven,

The variable ts_shift_hours is an output of the pvsamv1, pvwattsv5, pvwattsv7, and swh compute modules, so you should run one of those modules before attempting to read the variable's value.

Best regards,
Paul.
