[TYPO3-core] RFC #7626: Date/time handling is completely broken in 4.2

[Steffen Kamper]

Hi,

according to my investigations i like to show a patch for my supposed time 
handling

what i did:
* created a js var that has servers timezone offset
* on change of datetime field calculated the time of servers timezone
* removed offset in tceforms

i got fine results with my testing using
* server UTC +1
* client UTC +3

entered 17:00
after lost focus calculated to 15:00

please test it.

vg  Steffen
