Description
This PR adds the command
hwclock --systohcto thefake-hwclockscript located in/usr/lib/systemd/scripts/fake-hwclock.sh. The purpose of this addition is to ensure that after restoring the system time from the saved state, the hardware clock (RTC) is synchronized with the system time. This is crucial for maintaining accurate timekeeping on systems without a reliable RTC, especially in cases where the system may be rebooted or powered off frequently.Rationale
The
fake-hwclockpackage is intended to simulate an RTC on systems that lack one. However, after restoring the system time, there is currently no step that updates the actual hardware clock with the restored time. By addinghwclock --systohc, we ensure that the RTC is kept in sync with the restored time, improving the reliability of timekeeping across reboots.Changes Introduced
fake-hwclock.shscript now includes the commandhwclock --systohcimmediately after the time is restored usingdate -s @$savedtime.Compliance
pkgverremains unchanged as this is a minor enhancement.pkgrelhas been incremented to1.1to reflect the change and ensure proper tracking against upstream.
