Changing Hall of Fame debut time?

Hi there, I'm pretty new so nice to meet you all.

To start- I'm horribly picky about my game. In almost every single aspect.

Now I just beat the elite four and I thought I timed myself perfectly so that I would beat them at precisely 01:00

However, I misjudged it and it's now 00:59.

To put it bluntly, this tiny little detail is driving me crazy.

Is there a way I can modify this?

I'm very very new to pokesav, so if anyone could help me, I would really, really appreciate it!

I'm using a United Kingdom Soul Silver game.

Also, as an edit- I don't mind deleting the hall of fame data either. As long as it gets the time off the back of my trainer card. Are there codes for this? Or would I need to research pokesav?
