Date comparison weirdness

When I run jam, it always updates the following targets:

libs\regex\build\bin-stage\boost_regex_debug.lib
libs\regex\build\bin-stage\boost_regex.lib

i.e. it copies the originals from

libs\regex\build\bin\boost_regex.dll\gcc\*\runtime-link-dynamic

Unfortunately, the copy doesn't convince jam that the targets are
up-to-date, and it does the same thing every time. Weirdly, it
doesn't do this for the other binaries in that directory. Here are
the time stamps reported by explorer for one of the source-copy
pairs that it always copies:

source in build\bin\...

Here is the data for one of the files that *doesn't* get copied every time:

System is Windows 2000, jam built by the cygwin gcc using -mno-cygwin
with -DNT. Anybody know what's going on here?
