You're in my time zone, aren't you, so your hardware clock (UTC)
should be five hours ahead of the system clock (CDT). What are
the two times on your system?

  # hwclock --verbose
  hwclock from util-linux 2.36.1
  System Time: 1679611469.019755
  Trying to open: /dev/rtc0
  Using the rtc interface to the clock.
  Last drift adjustment done at 1650159782 seconds after 1969
  Last calibration done at 1650159782 seconds after 1969
  Hardware clock is on UTC time
  Assuming hardware clock is kept in UTC time.
  Waiting for clock tick...
  ...got clock tick
→ Time read from Hardware Clock: 2023/03/23 22:44:30
  Hw clock time : 2023/03/23 22:44:30 = 1679611470 seconds since 1969
  Time since last adjustment is 29451688 seconds
  Calculated Hardware Clock drift is 0.000000 seconds
