David T. Lewis uploaded a new version of Chronology-Tests to project The Trunk:

==================== Summary ====================

Name: Chronology-Tests-dtl.18
Author: dtl
Time: 27 January 2019, 1:21:59.414215 pm
UUID: 5411396e-c5fc-4517-97ef-5cf9e7aa5dea
Ancestors: Chronology-Tests-pre.17

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."
