Using a virgin 3.3.3 database, I get the following:
topaz 1> printit
{
(DateAndTime fromString: '2017-01-11T20:37:32.289+01:00')  printString.
(DateAndTime fromString: '2017-01-11T20:37:32.28995895385742+01:00')
printString.
(DateAndTime fromString: '2017-01-11T20:37:32.289+01:00')  printString.
(DateAndTime fromString: '2017-01-11T20:37:32.28995+01:00')  printString
}

Using a 3.3.1 database with Seaside and all loaded, I get this:
topaz 1> printit
{
(DateAndTime fromString: '2017-01-11T20:37:32.289+01:00')  printString.
(DateAndTime fromString: '2017-01-11T20:37:32.28995895385742+01:00')
printString.
(DateAndTime fromString: '2017-01-11T20:37:32.289+01:00')  printString.
(DateAndTime fromString: '2017-01-11T20:37:32.28995+01:00')  printString
}

I do not see the wildly wandering offsets; I do see a difference in how the
precision is parsed.

Can you provide more information about your configuration?
