The command responsible for that is sudo hwclock Apart from a small time difference between Knoppix and other distros, the effect you described with changing mountpoint dates has a perfectly natural cause.įirst, about the time difference: Most computers have a built-in battery-backed clock, so the system knows the correct date and time as soon as its booted up by looking up the BIOS time. While a device is mounted here, the mountpoint date shows as (epoch time?), but after unmounting the device ( umount), the mountpoint date reverts to its original date.Īny clarification you can provide for this strange behavior would be much appreciated. An already existing mountpoint will have its own date (e.g., ).
Unmounting the device ( umount) causes the mountpoint's date to change back to today's date. Others (SystemRescueCd, INX, and TRK) show 00h00. I mount a device (USB stick or hard drive partition) onto this mountpoint and look at its date.
