This sounds familiar and I found this old bug report:
https://groups.google.com/forum/?fromgroups=#!msg/comp.unix.solaris/VAf6v02EQZk/-Mook698kXYJ
"6996354 time-slider fails when daylight saving time ends"

The only other reference to that bug I can find is
https://github.com/bdrewery/time-slider/commit/4ba07f0c289bbb4dff9c4555c9eed1de2c90ffed

"Fix for 6996354 gracefully handle snapshot failure"
