From a Slack conversation with bytesized on Slack re: this issue:

Looking at the code, it looks like we set that to the time that the update download completed. That does seem a little bit odd to me. Ideally, the value would probably be written by the updater itself, but it doesn't really have the capability to do that. It might be more reasonable to set it when Firefox finishes restarting after the updater installed the update. Technically, the time would be a little late, but I think it's probably still be an improvement.

Just as another data point, this morning I updated Nightly and then found that within the Update History popup, the listed install time was about 2 hours prior to the actual install time.
