For the restore, when's the log from? I'd think that you've have log records that looked like:
1 - 1:45am
2 - 1:55am
3 - 1:05am
4 - 1:15am
5 - 1:45am
So a restore to a point in time would actually stop at transaction 1, not transaction 5. I'll check with Mr. Randal. He has a great post on what happens with SQL Agent, but I never thought about this.
Of course, if you have log backups at 1:59, you'd only get the first backup at 1:59. According to Paul's post, SQL Agent freezes from 2-3 (old time) or the second 1-2 (new time), so you won't have backup jobs then. You could manually run new jobs, but you'd then have separate files to restore to the point in time to.
