Keep in mind that most locations in the US will turn off daylight saving time today, but today is not the day that Switzerland will turn off daylight saving time. (Switzerland turned off DST a week ago.)
Those who are filing documents at the International Bureau — documents that need a same-day filing date — should check to make sure they know what time it is in Switzerland as of today.
The main point here is that for a US filer, everything is now “back to normal”. Whatever time zone offset a US filer is accustomed to between his or her time zone and Geneva, that offset is back to normal.
ePCT will tell you what time it is in Switzerland.
