Comment 58 for bug 365065

The transactions aren't invalid, they're just off by a day. You can edit the date on all of them if it's actually important.

We've just been discussing this in the developer list. We've decided to change the posted date timestamp to 1100 UTC regardless of timezone for 2.6.14 (2.6.13 release is too close to be sure of getting that change done in time). The local adjustment from that will remain the same day everywhere except the middle of the Pacific. We'll include a scrub function that modifies old data. We'll also make the data-load code able to read date-only posted dates; writing those will be in 2.8.
