As for daylight savings, that is likely always going to be a pain. JavaScript should know enough about the system it is running on to have the right offset. This puts the work of keeping daylight savings in sync on the operating system, where it belongs. Interesting, I’ll have to give that a read.

I'll have to update my example code to add the negative. Nice catch. I’ll have to update my example code to add the negative.

This means to get a proper offset, the result of that call needs to be made negative. After all, North American EDT is -0400, not +0400.
