plug-ins: fix failure to write IPTC TimeCreated

Browse Source 
The IPTC TimeCreated tag does not allow fractions of a second, while
Xmp.Photoshop.DateCreated (which includes the time) does allow this.

In our metadata editor we base our date/time on the last value and then
synchronize it with the IPTC date and time values.
While doing that, we did not check if the seconds had a fractional part.

To fix this we first check for the presence of a fraction by checking
for a dot in the time string.
Complicating factor is that a timezone difference may follow that,
which we want to keep if present. So we check for that too and
concatenate the parts we want.
