moissani,
thanks - but I can't hope that all users' browsers have such
security settings that I would be able to perform file operations
on local computer - even reading. Also I try to support various
versions of browsers, including Opera... It also complicates the
task.
coderWil,
as far as I know - vbscript is supported by IE only, unlike
to jscript. Moreover - anyway I would need to instanciate objects
moissani has mentioned about - to get the corresponding file
properties. But this is 'dead end' in common case, because of
browser security settings...
So, I make conclusion, creation date and last modified dates
are sensless fields. I could use only upload date instead...
(or make user to fill fields: file creation date, file
modification date - see in file manager and retype 🙂 ... )
And yes, it's already high time to make http header
information more extended, appending such useful things as file
creation and modification dates
