Problem with converting time

[Michael Doub]

time = 1489755600

Mac:      dateitems = 2017,3,17,9,0,0,6
server:   dateitems = 2017,3,17,12,0,0,6

Code:   get time
convertit to dateitems

I don't understand how the local time comes into play when converting a 
constant number of seconds.  The resulting date should be a constant as 
well.

What am I missing?
