Comment 14 for bug 139846

For what it's worth, here is the result of "cat /proc/driver/rtc" on my
system:

mythtv@mythtv-ibex:~$ cat /proc/driver/rtc
rtc_time : 00:03:51
rtc_date : 2009-01-22
alrm_time : 02:25:00
alrm_date : ****-**-**
alarm_IRQ : no
alrm_pending : no
24hr : yes
periodic_IRQ : no
update_IRQ : no
HPET_emulated : yes
DST_enable : no
periodic_freq : 1024
batt_status : okay
