Examining such omissions is a way of identifying areas where the POSIX specification might be usefully extended (for example, recognition of a 'u' element in a time of day to specify that it's universal time--this would allow a POSIX-style Godthab rule). --ado

My (unpatched) Windows 7 machine extends the 2010 rule [Fourth Sunday October to Last Sunday March] on to infinity. They have published at least two updates since then that I've been able to find that tweak the rules, and I haven't verified firsthand but have no particular reason to doubt they similarly extend the then-latest rules [Fourth Sunday January to First Sunday March, based on update description text] indefinitely, and expect to publish further hotfixes. -- Random832
