Was boot time reset?

[townsbg]

I noticed a few minutes ago that my up time under the performance tab in task manager says ~17 hours so I ran system information from command prompt and it shows System Boot Time: 5/13/2019, 3:35:38 AM. I put my computer to sleep last night before going to bed (well before 3 am) and it was still asleep when I got up this morning. Even if my computer blue screened last night and I had to boot it up this morning up time would only be about 12 hours. No one else can boot my computer due to full disk encryption so is it possible somehow that my system boot time was reset? If so is there a way to definitively determine that it was? I'm not finding anything in that event viewer from that time period. The last time I booted my computer was Saturday night so up time should show 2+ days.
