===== Time =====

  * :?: 2024/05/06: On GNOME, even though ''chrony'' does NTP sync, it doesn't seem to write it to the hardware clock which is usually wrong after a CMOS reset ((starting Firefox quickly after rebooting has a wrong system clock certificate failure error)); it's not known if this affects Server
  * This sets the hardware clock to the current system/OS clock
  * TODO: Figure out ''chrony'' command to do NTP sync

  sudo hwclock --systohc
