gash Posted March 1, 2014 Posted March 1, 2014 Hi, this may sound bizarre but I have come across a negative Total Editing Time. Is this possible and how? My theory is an existing file loaded into a PC with a system clock date prior to the current date and time. As I am assuming the time the file was opened and then saved would calculate a negative value from the historical system clock. What do people think? Quote
ReMark Posted March 1, 2014 Posted March 1, 2014 I think you have too much time on your hands? LoL Why is the negative total editing time of any concern? Is that how you or your firm tracts billable hours? Quote
gash Posted March 1, 2014 Author Posted March 1, 2014 No not at all a billable hours question, a concern over the integrity of the file due to a negative time value - any thoughts? Quote
ReMark Posted March 1, 2014 Posted March 1, 2014 The integrity of the file. Hmmm. Did you run the usual housekeeping commands on the file like Overkill, -Purge (regapps then all) and Audit? Does the file open properly? Any error messages during or after opening? Quote
gash Posted March 1, 2014 Author Posted March 1, 2014 yes, the file is all OK in terms of using it. Quote
ReMark Posted March 1, 2014 Posted March 1, 2014 Not sure what more you could ask of it then. But for the sake of argument let's say the file's integrity has been compromised. What if any choices does that leave you? Quote
gash Posted March 1, 2014 Author Posted March 1, 2014 Maybe none - but the negative Total Editing Time is now triggered intense curiosity! Thanks. Quote
ReMark Posted March 1, 2014 Posted March 1, 2014 There is one option. You could do the drawing all over again or have it sent out and redrawn by one of those offshore companies that charge like $100 for an entire D-size drawing. Quote
Dana W Posted March 1, 2014 Posted March 1, 2014 In the command line (or dynamic) type Time, then tell it to reset. Quote
Dana W Posted March 1, 2014 Posted March 1, 2014 Talking about having too much time.... Just out of curiosity I tested this by setting my system up to 3/02/14, created a drawing and added a rectangle then saved and closed. Then I reset the clock to the correct time, re-opened the drawing and did some edits. My create date is Tomorrow, my last saved date is today. The total editing time is not negative, it shows about 5 minutes. The total elapsed time is however, 0.002 seconds behind the total editing time but it is also positive. I may have created a wormhole. If I set my create date far enough into the future, I may be able to finish something on time for a change. I wonder what the Time command will say tomorrow. Next test will be to consecutively email the drawing to two people, each on opposite sides of the international date line from each other, let them make some edits, then email it back to me. According to the Theory of Relativity, the trip through the wires and antennae at nearly the speed of light should have an effect on the total elapsed time. Quote
gash Posted March 1, 2014 Author Posted March 1, 2014 Thanks, do you know how this can happen in the first place? Quote
gash Posted March 1, 2014 Author Posted March 1, 2014 Apologies, did not see your original post. What about setting the system to the past? Quote
RobDraw Posted March 2, 2014 Posted March 2, 2014 What if you do some stuff and reset the clock and then undo to a command previous to the reset? I can't test this ATM but the clock reset may not get undone. Quote
ROBP Posted March 2, 2014 Posted March 2, 2014 (edited) Did a few test with the clock did set it back five minutes (then reset, save and reopened a drawing etc etc.) never got a negative figure. I did not go to the cpu clock but could it have something to do with it if the timer works with the cpu clock i am shure it will afect the time if CAD program run's from it. I remeber way back in the past cpu clock was loosing time because of the week battery puttting a new battery and resetting the cpu clock did the trick next change in 6 years. r Edited March 2, 2014 by ROBP Quote
ReMark Posted March 2, 2014 Posted March 2, 2014 I'm reminded of Shakespeare's "Much ado about nothing." LoL Quote
gash Posted March 2, 2014 Author Posted March 2, 2014 Robp - thanks I think the test is to take an old file, set the computer clock back to the date of the file. Open for 10 mins, save and check Total Editing Time. ReMark - for me this is not quite nothing as I am looking at this from a amateur forensic perspective. Is this a bug or the clue to someone who may have tampered with a file. Quote
gash Posted March 2, 2014 Author Posted March 2, 2014 Robp PS, should have said check the Total Editing time whilst the clock is still set to an old date. Quote
ReMark Posted March 2, 2014 Posted March 2, 2014 It is not a bug. Maybe it is a CMOS battery problem. Sometimes a rose is just a rose. Quote
