It's not a bug. When you Print a value, it is internally converted to
a string using Str() semantics, so `Print x` and `Print Str(x)` should
always give you the same result.

The (documented!) difference between Str and CStr is that Str uses
localization information, like your timezone, and CStr doesn't.
Gambas stores dates internally in UTC, so when you

  Print CStr(Now)

you get the `Now` in UTC, which reads the same as two hours in the past
for you in Madrid. But when you `Print Str(Now)`, the Date is treated
as if it were relative to your current timezone instead of UTC, so you
get the same information printed that your wallclock shows you.

Also notice that the date format changes -- this is due to another part
of your localization. Str picks it up, CStr doesn't.
