time jumps in xen amd64/hvm instance

[Richard Kojedzinszky]

Dear Xen users,

I have a strange problem, my hvm instance sometimes jumps time forward. I made 
a little script to monitor this, and I am attaching its result also. I have no 
clues where to look, why this jump happens, but of course it is not 
normal. And as I have kern.securelevel at 2, ntp cannot correct this.

Could somebody help?

The amd64hvmntp.sh script is run by cron every minute.

Thanks in advance,
