Time travel paradox?

Well, i came home from school as usual, only to find out something was wrong. there was me, riding a motorbike, but I WAS CURRENTLY ON FOOT! For whatever reason the time was kinda twisted so that im in a room in my school and confused. There were my classmates too.

One of my friends told me to get a "time travel clock" and I was like "OOOOOOOOOOOOOOOOOHHHHHHH!!!" So I took it, but instead of giving it back to them I decided to use it. It's an analog time-travel device, no fancy digital clock or calendar, only has this weird year/month/date/hour/minute/second dials as well as something that looks like an odometer to display the current time. They used to switch the time are really sharp at the edge, so I was having a hard time using it but I managed to do it anyway.

I basically fast-forwarded the time, but NOT TOO FAR from when I took it, so my friends were still in the room. Curious, I also rewound the time, and I was at my granny's house. Time shows 6 am. I had nothing to do there, and they were confused as how did I even get this thing out of nowhere (well, this device manipulates BOTH time and location, so that it actually throws you into where you should've been).

I fast-forwarded again, then I was at my classroom with this TERRIFYINGLY ARROGANT teacher. He was an English teacher though. So I fast-forwarded it again cuz I cant stand him when he gets really pissed off. I was finally at home, where I should've been. Date and time is correct. I'm kinda glad that I finally managed to go home without my classmates bugging me about group assignments and whatnot :P

Curiosity kills the cat, few hours later I decided to use it again. I rewound the time, SO FAR FROM WHEN I WAS EVEN BORN. I decided to switch back the year, so much to the point where I feel like switching it feels faster or something. It was 3 July 1794, about two months after Lavoisier's execution was done. I didnt rotate the month day dial at all since I focused too much on the year.

Because I wasnt even born and the device doesnt know where I was at that time, it actually pulled up a map of what looks like the world map from the present days. It told me to choose an area I like, so I took Paris (it does have the search bar to make things quicker), and I clicked somewhere on the area. It then took me to a street and some people were confused about me coming outta nowhere, as well as my weird appearance (well, such casual t-shirt and jeans look absolutely weird in the late 18th century). I literally didnt know what they said cuz everyone was talking in French, so I just shut up and walk.
