It appears that there are no reliable dates or times on the Stacker News wallet history page, and that is making my tax spreadsheet very sad.
Many rows in the table lack any timestamp at all, and even those that do have one record the creation time of the post, not what time I spent my sats voting on it.
In the US, in order to file taxes using the specific identification method, it is necessary to refer to exact dates, times, and market prices. Of course, that burden is on me, but it would be nice to have records to fall back on.
