Thanks. I'll try out your snippet later today. What's confusing to me is that I tried about the same approach as yours but without using the sugar `=>`, and it didn't work because it failed to compile because the `newTimeZone` needed gcsafe proc args.
This fails: [http://ix.io/1L6u/nim](http://ix.io/1L6u/nim) >From my discussion on gitter: >[https://gitter.im/nim-lang/Nim?at=5cf9d0e7f3a60a79a468a3da](https://gitter.im/nim-lang/Nim?at=5cf9d0e7f3a60a79a468a3da) I'll then also try out this suggestion by @GULPF: [https://gitter.im/nim-lang/Nim?at=5cfa28266fc5846bab7808e1](https://gitter.im/nim-lang/Nim?at=5cfa28266fc5846bab7808e1) I am failing to understand the basic requirements of how to make gcsafe procs, but I need to generate that offset int at run time from an outside proc.
