Can you elaborate on this a bit more?

I just use it to do a one-time adjustment. I agree with you that the 
aforemented format does not fully specify a time zone (I guess I used the 
wrong subject in the first place. :-)). DICOM only uses the ZZZZ as the 
offset from UTC and that's how we plan to use ZZZZ. We'll convert it to UTC 
time as soon as it is parsed.

Thanks,
