Kenny.
Dec 24th, 2037 is the new Y2K.
32biit based web software can't deal with a date beyond that. In this case it's a web site thing not SONAR.
It's gonna take a conversion to 64bit based web software to make the date like 96.4 Feb. 987623.
Congrats on uncovering (for like the 9,365,782,527th time) a most serious bug.
