I would have named this variable daylightType instead.

It's unfortunate that we have to convert WCHAR to char here.
I would use ascii().data() instead possibly allocating String as a local variable.

Okay, I withdraw my r+. We need to be more careful here. I thought DaylightName could only be 3-letter abbreviations but this apparently isn't the case. It could be a full long timezone name.
