How do I set the date on my Hwclock?
Just type hwclock, which will display the date and time of your system’s hardware clock. This is the same date and time that you’ll see from the BIOS screen. You can also use option -r, or –show to display the date and time.
How do you set time in Arch?
Setup ntpd (enabling it as a service is not necessary). Set your time zone correctly. Run ntpd -qg to manually synchronize your clock with the network, ignoring large deviations between local UTC and network UTC. Run hwclock –systohc to write the current software UTC time to the hardware clock.
How to set TZ, date and hwclock?
Then, assuming the hardware clock keeps UTC, what is the time in the local timezone?” “First, tell me the system time in the local timezone.

How to set the hardware clock in Toradex?

What are the date and hwclock commands in Linux?
date and hwclock commands. Linux maintains two clocks: the hardware clock and the software clock. The battery driven hardware clock maintains the time while the computer is turned off. During the boot, Linux reads the hardware clock and sets the software clock to the value it retrieves. You can manually set the software clock with the date command.
What does UTC and localtime mean in hwclock?
–utc tells hwclock that the hardware clock keeps UTC, and –localtime says that the hardware clock keeps the same timezone as the system clock. (More precisely, it says that the hardware clock keeps the same offset to UTC as the system clock currently does — hardware clocks often don’t know whether DST is active.)
