Before we start, however, it's necessary to determine whether your incorrect time is down to a synchronization issue or if it's just a problem with your time zone.

You can just enable the daylight saving toggle or change your time zone in settings to remedy this.

If your minutes and hours or just minutes are wrong, it's more likely that you have a synchronization problem. You can fix this in a few seconds by performing a time synchronization in Settings or the Control Panel. You can also use the time synchronization command in CMD if you prefer.
