Importing tags from Simplenote changed "Date Modified" for some notes

[mydwynter]

I hadn't updated nvALT since June, so I did it today. And for some reason, doing so caused twenty-three old notes to suddenly become marked as modified that day. It seems that all of these notes are associated with at least one of three tags. (But not all tags associated with those twenty-three notes were affected.)

I presume it's a bug in the nvALT update process? Or perhaps not. What I'm really curious about is whether I can change the "Date Modified" somewhere, so I can get them back into some semblance of order. Fortunately, the change didn't happen over on the Simplenote side, so I know where in time they belong.
