I am currently using this script to do some revision control with CAD files using DraftSight. Is there a way to do this same thing but, from the script menu while in DraftSight itself. Instead of clicking save periodically I would like to click the script and have it time/date stamp the saves so I have a history of my work.

I used your code to "synchronize" pictures (ab. 650) from various camera devices in my family (3 smartphones, 1 camera).
In order to get all pictures in a useful sequence I also had to add the time of day (hour, minute, seconds).

More problem I had is that our devices do NOT run correctly in regard to time – e.g. the camera "gains" about 2 minutes every month (here: +720 sec), my smartphone is hardly ever online and slow (-210 sec) ... so I added a "correction dialog" asking for a number (in seconds) to be subtracted or added to the "original" result.
(I had to find pictures taken at about the same time to get comparison values for these corrections.)

Here are my additions:
(* Time correction, in front of "tell application finder": *)
global plusMinus
set plusMinus to 0

(* Asking for value, put after "set the source_folder to (folder of the front window) as text" *)
set Corrections to display dialog "Insert number of seconds (also negative):" default answer "" buttons {"Okay"} default button 1
set plusMinus to text returned of Corrections as integer

The main calculation of course happens in "on dateFormat(theDate)":

(* Adding values for time of day, put after "set b's month to January" *)
set hou to (((t - plusMinus) / 3600) - ((t - plusMinus) / 3600 mod 1) as integer)
set min to ((((t - plusMinus) - hou * 3600) / 60) - (((t - plusMinus) - hou * 3600) / 60 mod 1) as integer)
set sec to (t mod 60)
if (hou < 10) then set hou to "0" & hou
if (min < 10) then set min to "0" & min
if (sec < 10) then set sec to "0" & sec
(* Change the "tell" part of "on dateFormat(theDate)" to: *)
set date_string to (text 1 thru 4 & text 5 thru 6 & text 7 thru 8 & "_" & hou & min & sec)

("mod 1" => "as integer" rounds values, sometimes up, sometimes down ...
"if (xxx < 10) ..." => get a leading zero: "180704" instead of "1874".)
Please be aware that I am not an IT professional – be lenient with any "stupid" algorithms ...

Last point:
one of our smartphones (or its transfer app) saved pictures with the "current" date – so I had to replace "modification date" in the above original code to "creation date" to get a valid result (I did NOT put this into another dialog).
