Bug #8376

utc method changes original time object

The utc method changes the original time object when called.

For example when on a system with a CET timezone.

t = # CET
t.utc # UTC

Time#utc is destructive method.
Use dup if you want a copy.

That seems the point of this issue. The behaviour is inconsistent. t.utc! should be the way to destroy t in the example. This should be changed... ruby isn't PHP.

I admit this is a bad design, but changing it introduces incompatibility.
We don't consider it as a bug (thus we rejected).
Submit feature request instead, if you really want to change.
Maybe fixed in the future, if we can provide proper migration path.

You can use Time#getutc or #getgm.
