This does not seem to be a bug in CLAM client, but a misconfiguration on your raspberry pi. Here is a link to get you started, but that's the best i can offer you as i don't have one to debug by myself:

https://stackoverflow.com/questions/41848227/debian-linux-raspbian-raspberry-pi-time-offset-is-65s-ahead-of-utc

NTP can be inaccurate if you get the wrong mix of peers. My main router has 5 external peers, and all are at least 500ms off (both +ve and -ve) my computed time. One is at +2.3 seconds offset. These are all supposedly stratum 2 servers, learned from pool.ntp.org.

My PI has correct time - same time I have on my Main PC and on the Phone (I am using time-based 2FA, so my time has to be correct)
Bud I tried to:
Stop clamd
move .clam to .clam_backup
create new .clam/clam.conf
start clamd with no blockchain from scratch

Then I got peers with +-1s timeoffset.

Then I switched back to the full synced chain and again +-85s timeoffset.
I tried to delete peers.dat, no change

See below
at the 10:21:21 I got new block with error block timestamp too far in the future
at the 10:25:20 The Block with timestamp 10:21:20 is officially accepted but is considered as "already have"

So I don't know if I can start staking, as I got forked in December (after 2 years of smoothness stakig) and I don't want to repeat the same issue...

Also I am considering, that the size of the clam overgrew what RPi can handle - are there other RPi stakers here?
