Install the "posixrules" timezone link in MSVC builds.

Browse Source 
Somehow, we'd missed ever doing this.  The consequences aren't too
severe: basically, the timezone library would fall back on its hardwired
notion of the DST transition dates to use for a POSIX-style zone name,
rather than obeying US/Eastern which is the intended behavior.  The net
effect would only be to obey current US DST law further back than it
ought to apply; so it's not real surprising that nobody noticed.
