SD,
As noted, seconds-from-dateTime() is defined both in XForms and in XPath 2.0. For some reason we have never noticed this conflict.
In XForms 1.0 and 1.1, its signature takes a string, and its meaning is different from XPath 2.0's: it returns the number of seconds since 1970-01-01T00:00:00Z.
The XForms 1.1 function is the one kicking in in Orbeon Forms, and this is why you are seeing a large number.
I am not sure we have a workaround for this at this time. As I don't like so much the time/date functions from XForms, I am tempted to say that the XPath 2.0 function should be the one kicking in instead, and that xforms: seconds-from-dateTime() would give access to the XForms version.
Thoughts?

correct - that's what the xforms 1.1 seconds-from-dateTime should
return. It doesn't extract the seconds part of the dateTime value but
computes the seconds since 1970-01-01T00:00:00Z (1).

hmm - i'm not sure... regarding minutes-from-dateTime, there's no
XForms 1.1 function with the same name, so it seems that the XForms
functions take precedence if there's a name conflict, but the XPath
functions are still available. So, the next question would be how to
persuade the XForms processor to handle seconds-from-dateTime as XPath
function...
