Okay this is quite peculiar
I set the time through the WEB interface, and this worked. After rebooting clock was now saved to the hardware clock.

- How do you mean , seems like the clock command allows you to set time and date ?

It does, but it does not write to the hardware clock, so when the ISR is rebootet, time is incorrect

Here is how to set up the clock manually :
Can you post-show version, like to see your reg value.

- Could you try entering the command clock calendar-valid in configuration mode (conf t) and try the update and read commands again afterwards. This command makes sure that the hardware clock gets trusted.

unfortunately this dosent work either.
Could it be that these commands have been depricated?

I have ISR 4K with a different version: below command works fine -
can you post the output clock? ( config or # mode)
4.3Clock ManagementClock management is restricted to the privileged administrator. Use the commands below to configuring the time and date:
router(config)# clock timezone zone hours-offset [minutes-offset]
router(config)# clock summer-time zone recurring [week day month hh:mm week day month hh:mm [offset]
]router(config)# clock summer-time zone date date month year hh:mm:ss date month year hh:mm:ss [offset]
router(config)# exitrouter# clock set hh:mm:ss date month year

- How where you able to verify this statement ?

I am just wondering: maybe that internal hardware clock, which is a battery-driven, onboard device, is broken, or the battery is empty ? Not sure how to check that though...
02-09-2020 02:01 AM
It is battery driven, and the router has a battery on the mainboard (i opended it)
Im pretty sure it is not broken, since the router remembers the hardware clock, my problem is that i cant adjust the hardware time.

- Not sure, you may want to issue show tech-support , analyze the output and check if there are any references to the hardware clock and or it's status. Further more check the link below and if the command-set (system verify) is available try them out and generate a detailed report. Then also look for references concerning the hardware clock :
