David- I sort of ran into this same issue about a week ago, when I was called in at the last minute to do a REVENANT screening at a location where the Doremi had been shut down and not used for almost 3 months.
According to KDM e-mail from Deluxe, my 'key' was good at 5pm local time. --------------------------------------------------- ![-](http://www.film-tech.com/uploads/uploads0503/Email_Pic.jpg) ---------------------------------------------------
The actual KDM XML file looked like this: ---------------------------------------------------------------------------- ![-](http://www.film-tech.com/uploads/uploads0503/KDM_XML.jpg) ----------------------------------------------------------------------------
On the Doremi, it came up like THIS: ![-](http://www.film-tech.com/uploads/uploads0503/Doremi_Scrn.jpg)
However, while trying to figure this out, I found that on one of the 'set up' pages in the Doremi,there was "UTC Offset" input of 480minutes, or 8hrs. (Which still makes no sense, since 0000UTC(-480min)= 1600 local, not 1700)
Long story short- - I went in early the day of the screening and the KDM became active at exactly 1700PST, as stated in the Deluxe e-mail, even though I still haven't figured out the math.
The server was a DCP-2000. No ShowVault. I don't have my notebook here today, but I believe the software was all up to date.

quote: Lars Goldschlager I take the chance to ask whether producing the KDMs using an UTC time zone is a industry standard practice, and why/how it came about.
Right now we're still servicing KDMs mostly for our own country only, but as more movies we lab are being sent internationally my normal procedure is to produce KDMs in the time zone where the screen is located.
The reference for secure clocks and KDM timeframes is and has to be UTC. However, if your KDM creation tools allow you to use local time and 'hide' the real mechanics behind it, that doesn't make that reference system invalid. The software I use always uses the time zone/local time of the machine it is running on, but then writes UTC to files. When I want to create a KDM with a very precise time frame for a different part of the world, I set my machine to that time-tone, create the KDM, and then that timezone is used to calculate the proper UTC that goes into the KDM. At the remote site, the UTC is again transformed into local time, since the server/SMS/TMS uses local time.
