It is normal for the average wall clock. Of course, this can be adjusted, but without watch/clockmaking knowledge it is impossible, because first you need to find out which part of the movement is causing early chiming - and there are plenty of them.
Super fine adjustment can be found only in top of the range clocks. Hundreds of hours of craftsmenship are spent to adjust and fine tune them. That's why they cost a fortune.
If you can not live with that early chiming, you have to bring your clock down to the watch/clock repair shop and ask for help. Be ready to pay quite a money, as this job takes the skill and a lot of time.

Rate me, please.

SOURCE: How do you syncronize the chimes to the actual

Are the hands held on by a nut? usually you can remove the nut with your fingers or a pair of pliers wrapped in cloth or duct tape to prevent scratching.
Before removing turn the minute hand (minute hand only and clockwise only; do not manually turn the hour hand and never counter-clockwise) turn the minute hand clockwise until it chimes at an hour mark.
Then remove the hands and and place them pointing to the correct time.
If you are uncomfortable with this I recommend taking it to a clock shop or jeweler that sells clocks. If it is inherited, it may need some maintainence (oiling and regulating) anyway.

Try www.klockit.com. You can replace the entire movement for about $5 including new hands. You can select from an assortment of hands that will probably match the style of what you have and use those if the old hands don't fit the new movement. I've bought several movements from them over the years. For a few more dollars you can upgrade to an "atomic clock" movement which synchronizes with the US time signal and even sets DST automatically.
