Is the DateFormat read only?

[Alex Tweedly]

But that will only work for those time zones whose variation from UTC is 
an exact number of hours.

the internet date has 4 digits so that it can handle hour and minute 
variations - you could change

   subtract (char 1 to -3 of last word of the internet date) from item 4 
of tTime

to

   put the last word of the internet time into tmp
   subtract (char 1 to -3 of tmp) from item 4 of tTime
   subtract (char 1 of tmp & char -2 to -1 of tmp) ) from item 5 of tTime

and then you would be handling all cases correctly.
