There are some things you can do. First check the hardware clock setting in your BIOS. It is maintained by an onboard battery on most systems. If this is an older machine, and it is drifting, it may be time to replace the battery.
Second, install NTP. It is available for most distos. Here is a sample of what to install.
Once installed, your system can be configured to sync with an atomic clock. Most governments have one. Of course you need internet connectivity for it to sync.
