There are many great images in this section whose scientific value would be much improved if the time they were taken was indicated. An accuracy of a minute or two is usually sufficient for solar work and it doesn't take a lot of effort to do the job properly!
Here's my effort at today's huge "hedgerow" prom:
2009 Oct 04, 1158 UT. Solarscope SV60, 4x Imagemate, Imaging Source DMK41 camera. Transparency good, seeing moderate to poor with considerable boiling.

Just wondering, who's using these images for their "scientific value"?
Nice shot!

Well, if images are timestamped, it helps those of us who are not able to watch all the time see how fast things are changing. It's also useful (scientifically) for those of us who are contributing images to see how our processing compares with others who are imaging the same object at (about) the same time.
Anyhow that effort involved is so minimal that any benefit needs only to be correspondingly minimal to be worthwhile.
And it's GOOD PRACTICE - one day you MAY observe something that no-one else does, if you aren't in the habit of documenting observations / images you may not be able to do so when it's important.

Sounds good, Brian.
I used to put the time, orientation and Carrington Rotation on the shot but have abandoned that in the last few years. Guess I switched from contributing to science to creating artwork. But that's just me...

I agree if for no other reason if helps me understand who my drawings compare to similar drawings and photos taken near the same time, or how a feature has evolved. Thanks.

I also find the times very helpful to order the images chronologically when a bunch of people post them on the same day.
And I like to find images taken near when I did my sketches to compare.
Cheers,
-- Jeff.
