Until I went looking to reset my clock I hadn't thought about it either until I seen that. Actually, maybe you should care because if it's true that the steem keychain can be used by others to make transactions/changes, maybe that's how whatever it was a few months ago you were warning about some change that happened and people needed to see if there had been a change in some number formatting.

Anyway, I am still at this point:

Missing Posting Authority sunlit7Transaction failed to validate using both new (hf26) and legacy serialization

and what that actually means and how to correct it. If you don't know how, and it's hard to imagine because you know everything, do I need to download that discord thing again and if so where do I ask for help resolving my problem.
