Do not use #makeUTC in DateAndTimeTest>>testGetSeconds because it modifies magnitude.
=============== Diff against Chronology-Tests-pre.17 ===============
Item was changed:
----- Method: DateAndTimeTest>>testGetSeconds (in category 'Tests') -----
"Verify that getSeconds represents whole seconds in the local time zone. For
a given instance of DateAndTime, changing the time zone offset changes the
local representation, but does not affect magnitude (time since a defiined
epoch). Therefore, if time zone offset changes, the asSeconds value should
not change, and the getSeconds value should change to reflect local timezone."
