Not sure where else I could have asked this question, so here it goes.
I have been using wammu/gammu on my Ubuntu PC to connect to a Sony Ericsson T630 mobile via Bluetooth - all works fine there. In particular, there is a feature that I like in wammu, called "Synchronize time": instead of setting the current time and date manually in the phone, that feature will automatically sync the clock of the mobile to the clock of the PC.
Recently I got a Nokia 112, which apparently runs the S40 operating system. And every time I power it down and take out the battery, it asks me to set the current date/time manually again, which I find extremely irritating.
So, I managed to connect to the Nokia 112 phone from wammu, and issue "Synchronize time" command - unfortunately, it failed; the logs report something like:

So, apparently this phone can communicate via AT commands over Bluetooth; it's just that, apparently, it doesn't support the AT+CCLK command which wammu uses to synchronize time. I've also found:
- AT Commands - Nokia Developer Wiki (labeled: Compatibility Platform(s): Series 40, Symbian)
- Support Guide for the Nokia Phones and AT Commands (pdf)
... which seem to confirm that AT+CCLK is not supported by Nokia phones (at least not S40 ones).
Now, what motivated me to post, is this that I read in the wammu log:
Tue 2014/06/03 13:14:47: 1 "AT+CGMI"
Tue 2014/06/03 13:14:47: 2 "Nokia"

Now, this Nokia 112 actually supports SyncML, and I already managed to use syncevolution to synchronize address book contacts between the Nokia 112 and the PC (over Bluetooth). Unfortunately, it seems syncevolution is only good for contacts, calendar items and notes/todos (e.g. it doesn't backup SMS messages, apparently) - and I also couldn't find any reference if it supports synchronizing the mobile clock with the PC time.
So, my question ultimately is: if AT+CCLK is not supported by these phones, is there any other way - maybe SyncML? or something else (maybe OBEX) - that would allow me to synchronize the clock of the mobile with the current time on a Linux PC, over a Bluetooth connection?
Well, not exactly an answer to this, but just I thought I'd post:
Turns out, on this phone, there is a setting, that can be reached by:
Menu / Settings / Date and time / (scroll down, and there is) Auto-update of date & time
There are three options there, On, Confirm first, and Off - by default it is set to Off. I changed that to Confirm first, turned off the phone power, turned it back on again; at boot it asked me something like "Update current time?", I clicked yes, and so the time/clock got updated automatically.
But I'd still prefer, if I could synchronize time from the computer -- so the question is still open...
