As I reported a week ago, the usual autumn thing happened with time zones. A week ago Europe “fell back” with daylight saving time.
Now today the US also “fell back”.
For the past week, US filers had an extra hour available to get a same-day filing date for filings at WIPO. A US filer could file as late as 5PM (Mountain Time) instead of the usual 4PM, and get a same-day filing date.
Now it is back to normal. The time of day to keep in mind is once again 4PM Mountain Time.
