On the evening of December 31, 2023, or on the morning of January 1, 2024 (depending on your timezone), we expect some of our SyncBox products to quit providing reliable sync until rebooted. We have set up a website at http://packetflux.info/glonassrollover/ to provide more information about this issue. If you are not the technical contact at your organization, please make sure that a technical contact is made aware of this issue.
