What is the purpose of the msRun startTime attribute? It's an
xsd:duration type so using it to store a point in time seems odd. But
the documentation "The time at which the run was started." clearly seems
to refer to a point in time.
Andrew, a straightforward compromise here is to use msconvert to write
out just the file header and the first spectrum in mzML. Something like
'msconvert data.RAW --filter "index 0"' should do the trick. Then a
simple grep/regex over the file should get you the startTimeStamp.
Hope this helps,

Thanks for the pointer! Unfortunately, I am using xcms (1.21.7 under
R 2.11.1/bioconductor 2.6) to read the .mzXML files, which does not
currently support reading .mzML files in the release version - I think
it is possible with a custom development build (http://
metlinwiki.scripps.edu/mediawiki/index.php/EnableMzMLSupport) , but
not (easily) under Windows, which is what I will be using.....

If you convert the RAW files to the *mzML* format using msconvert, then
the date will be there in the form:
<run id="OR20100622_uk_06_1825_1a_34_1"
defaultInstrumentConfigurationRef="IC1"
startTimeStamp="2010-06-23T01:30:33Z"
defaultSourceFileRef="RAW1">
