While a little late perhaps...

 

If trying to image an asteroid occultation, you need to have very accurate times to be able to contribute your observations, using free NTP software, you can have your system clock within some milliseconds of UTC. Having image files stamped at the beginning of the exposure would allow occultation observers to meet this severe time accuracy constraint, which is why it is a very important feature.

 

I've just upgraded to 3.1.1 and hope this feature has been implemented!

Perhaps I should explicitly ask. Has this been implemented in 3.1.x (namely that image files are time-stamped with the system time when the exposure starts?)

No, not implemented in 3.1 :(

 

Can you please start a thread in the Feature Suggestion Box forum.  This is where I go to fix minor stuff when I'm board :)

The time stamps -are- not indicative of when the shutter opens in any release.

 

They are down to milliseconds to make sure they are unique and do not override one another.

 

Time stamps are at the end of the image capture and processed, e.i. exif read/write and copied to your download folder.  I should/need to change it so it actually reflects the actual time the image was taken... when the shutter closed... but haven't gotten to it.

 

As Rick said you should upgrade to 3.0.3 and I should be releasing 3.1 sometime in September.  Upgrades will be free as usual.

Thanks for the clarification. I suspected it would be that way since the interval between consecutive time stamps can vary by as much as a second.

 

Guylain, I'm surprised you need the time down to milliseconds to separate consecutive image files. With my equipment (350D camera and 32-bit Vista laptop), the minimum interval between consecutive images at maximum resolution is several seconds. A time stamp with a resolution of one second would be more than adequate.

 

I will look at version 3.

Yes... but with the premium edition it is possible to have 2+ cameras connected and this ensures that no file will get the same name even they are configured to use the same file name template :)
