I probably have a dead CMOS (BIOS main board?) battery. When I power on my computer the date and time is reverted to an old date (something like 2009-1-1).
So, I checked the following:
$ cat /proc/driver/rtc
rtc_time : 09:43:09
rtc_date : 2023-03-23
alrm_time : 08:34:43
alrm_date : 2009-01-01
alarm_IRQ : no
alrm_pending : no
update IRQ enabled : no
periodic IRQ enabled : no
periodic IRQ frequency : 1024
max user IRQ frequency : 64
24hr : yes
periodic_IRQ : no
update_IRQ : no
HPET_emulated : yes
BCD : yes
DST_enable : no
periodic_freq : 1024
batt_status : okay
Can somebody explain me what do these mean? I haven't found anything useful after googling it. Especially the fields alrm_time , alrm_date, and batt_status.
