Hi Eric,...
Aahh, these two issues make the question even more komplex. especially
the timestring issue... I guess I will keep this in mind untill I have
an Idea.
Thanks for explaining this to me.

In theory, you could modify the store.php script so that when sending
the current TW contents to store.php, you also send the
document.lastModified value. Then, store.php could compare that value
against the date of the hosted version of the file to ensure that the
date on the server is not more recent than the date sent from the
currently loaded document. If it is more recent, it could reject the
save and return an error. Then, to resolve the problem, you would
export the changed tiddlers from the TW in the browser (saving the
export file locally), and then reload from the server, and then import
the changes to merge them. Then save to the server again.
I say "in theory" because I don't have access to the version of
store.php that you are using, and I also don't have a server on which
to test the changes.
Some possible issues:
* the document.lastModified value is only valid if you loaded the
document via http or https protocol. If you are working from a local
file copy, that value will be the current date/time, regardless of
when the file was actually saved.
* WebKit returns the time string in UTC; Gecko and Internet Explorer
return a time in the local timezone. Thus, you might have to install
the "Browser Sniff" plugin (from the TW Official Plugin Library) in
order to detect which browser is in use, and then do some conversion
to match the time in use on the server (which might also be either UTC
or local time)
