Problem with converting time

[Michael Doub]

Richard here is another example:

time = 1489752000

mac: dateitems = 2017,3,17,8,0,0,6

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

I just wanted to double check that I was showing you good comparison 
since I am copying from multiple windows of debug output.
