1. This has been brought up before, said no to for multiple reasons, read old topics
including what Awi said, and why do you need to know the exact time it upgrades? it's not like you miss out on something if you do it a few hours later
2. Probably easy enough to implement. if it was done, it wouldn't be a shop item, very few would bother buying it, especially when you can just use a calculator to work it out.
likely won't get done any time soon
