RFR JDK-8155616: java/util/zip/TestLocalTime.java fails intermittently with storing mtime failed

[Xueming Shen]

Hi Amy,

I finally got to the bottom of this failure. It appears the timestamps that
trigger the failure are those that (1) < 1980 and (2) within the 
daylight saving
time gap, which means the local date-time is actually not valid, for example
1968-04-28/2:51:25, this ldt should be adjusted to 3:51:25 when switched
to summer time. This is really a corner case that should not have any real
impact to real world use scenario. The implementation itself is correct. 
Just the
test case need adjusted. Please help review.
