Interesting question. Unfortunately I’m not at work now, so I can’t test this on the laptop I have been referring to. But I’m at home, and I started a new DWG file with AutoCAD 2014 that I just installed on Sunday and which has never been used until this minute. There is no network at home here except for a Windows “Workgroup,” but AutoCAD is installed locally and the DWG file and lock files created are automatically placed in the default C:\Users\Carl\Documents folder.
There are 3 screen captures attached, which show the dates and times of the DWG file, the DWL file and the DWL2 file:
Drawing1.dwg – date created & modified: 8/30/2012 12:41 PM
Drawing1.dwl – date created & modified: 9/1/2012 5:32 PM
Drawing1.dwl2 – date created and modified: 9/1/2012 5:32 PM
It makes absolutely NO SENSE whatsoever! Why are the dates of the dwl/dwl2 files the same for each while the dwg file has a different date completely? I feel like I’m in the Twilight Zone…
Well, I have a resolution for the work laptop: I was able to log into the Linksys NAS (Network Attached Server) device at work. And when there, I discovered that the server itself had a system date of 12/11/2007 and time of 3-something AM. The server had been set up to get its time automatically from the default Network Time Protocol (NTP) server at ntp.jst.mfeed.ad.jp (a Japanese website). But that NTP site was apparently not sending the servr the correct date & time. So I changed the server setup to have date and time set manually, and used my own laptop's current date and time as those the server should copy. Now when I update a DWG file or make a PDF using the DWG-to-PDF driver, the modification date visible on the file (or seen inside Acrobat) are correct. Yeah!
This does not, however, explain the test I performed earlier, on my computer at home, which is not connected to any NAS server device and where AutoCAD 2014 creates all its files locally on the C:\ drive. The computer's date and time are correct, but as noted in the attached screen captures of that previous message, the file dates used are August & Spetember of 2012. This remains a mystery to me. But I'm not going to worry about it, as I rarely use AutoCAD at home.
Thanks for the suggestions, especially for making me look more closely into the settings of the NAS server device, which was the correct way to go.
