Sync alarm time with sunrise

I would love to syncronize my alarm time with the local sunrise time instead of a fixed time.(sunrise alarm does this but it not nearly as great as sleep as android in every other way)

I also would like this feature. After all, starting day this way allows one to ignore DST (summertime) changes and it seems to be the most natural way.
