I need some help reassuring one of our customers about the date/time problem on his TurboLaser running D. UNIX v3.2d-1. After a power loss the date of the system changed to 2025 (the remaining part of the date/time hasn't changed). I booted to single user mode, set date, mount -u / and rebooted. This worked. But a week or two later the same story repeated again. After reading the relevant notes here and in the TurboLaser conference I gave the following explanation to the customer: "Since the year is stored in the root file system's timestamp and the power outage left the file system metadata in an inconsistent state therefore it's not surprising that the year has changed. It's not an expected operating condition to cut off the power." Was I right or the should explanation be completed or did I tell him total mess? Thank you in advance and regards, Laszlo

| 10054.1 | Does the console know it's UNIX? | WIBBIN::NOYCE | Pulling weeds, pickin' stones | Thu Jun 05 1997 14:29 | 17 |
I *think* the correct answer is different. OpenVMS, Digital UNIX, and probably Windows NT all have slightly different ways of using the battery-backed wristwatch chip that the hardware uses to implement a long-term clock. For example, VMS stores local time, while Digital UNIX stores UTC. Rather than take the risk that the time would be off by just a few hours (and not be noticed for a long time), Digital UNIX chooses to store an offset date. If the console believes it's in "OpenVMS mode" it will misinterpret the UNIX offset date. Are you seeing the wrong date only in the console, or also in Digital UNIX? Or did you reset the date in the console, thus confusing UNIX? I think if you keep your hands off it, and reboot after the power is restored, the date will be OK from within UNIX. | |||||

Thank you for your answer. Perhaps it hasn't turned out of my note clearly but I've never adjusted the date in console mode but only in Digital UNIX (and in single user mode!). The OS_TYPE console variable was UNIX, which means (I think) the console was in UNIX mode. So I don't know now where I am. Could you please, give me an explanation why only the year portion of the date changed after the power outage? Rgds, Laszlo [Posted by WWW Notes gateway] | |||||
