Php input date/time as timestamp with timezone

Question

This is a nightmare!!!!
I have numerous databases, all of which use timestamp format
date/times, which are easy to echo according to user timezone
preferences using putenv ("TZ=".$_SESSION['MM_UTZ']); and echo
date($_SESSION['MM_UTF'], ($whatever));
The only problem is, I have only used these for stamping
"date created" or "date edited" values using Time()
What I am trying to achieve is:
User 1 in UK enters date and time, using a javascript
datetime picker (which normally enters data into field in Y-m-d
H:i:s) and the php inserts this in timestamp format according to
timezone.
User 2 in US looks at date and time and this is echo'd
according to his timezone.
Sounds simple...
I have managed to get so far with the new DateTime object
which incorporates the user timezone preference ($utz)
$ndttime= new DateTime($timefield, new DateTimeZone($utz));
I can then echo this effectively using
echo $ndttime->format('$utf'); ($utf being user timeformat
preference)
My stupid problem is trying to get the $ndtime into the
database!!!!
I know this sounds ridiculous but I use the DW insert wizard
which only uses values from a form and if I echo $ndtime into a
hidden field, it doesn't process this value in time.
I attach the current insert script.
Is this simple?
Heeeeelp.

how does this format when you echo to the page
echo $ndttime->format('$utf');
This will echo as a date/time object - i.e. Y-m-d H:i:s, but
the $utf variable is a session variable with user time format
preferences, so it could be D, d/m/Y H:i:s or m-d-Y H:i:s
etc.
