Good morning AskPerf! Anshuman here with a quick post on timestamp differences in Windows Explorer when accessing FTP sites.
On Windows 7(SP1), Windows 8, and Windows 8.1, you access a folder using ftp by opening an explorer window and typing in the FQDN FTP URL in the address bar. In the FTP folder view, if you access the properties of a file, you may notice that the Modified time in the properties of the file may not match the Date modified time stamp displayed in the detailed view in explorer. See screenshot below:
This behavior can be observed if the local time set on the machine from where you access the FTP folder in explorer view is set to a Time Zone other that the UTC time. In this case you will see that the Timestamp of the item, when its property is accessed is displayed as UTC, while the timestamp that we see under the Date modified column for the same file is shown as per the Time Zone that’s set on the machine.
Please note that both the timestamps are correct. The difference is due to the Time Zone bias added or subtracted from the UTC time.
