Pending changes to time of Newfoundland Time Zone for Daylight Savings Time

Where is the 'time of change' recorded in this data?
As I understand the legislation, having found
http://www.assembly.nl.ca/legislation/sr/statutes/s23.htm (which is, I
think, the current Standard Time Act), the intent is to alter the local time
at which the switch is made from the unusual 12:01 am to the more normal
02:00 am. It is not clear to me that the existing table recognizes this as
the time when the change occurs. I don't think the offsets from UTC
(Greenwich Mean Solar Time is mentioned in the statute) change; it is 2.5
hours west of (behind) UTC during daylight time and 3.5 hours west of
(behind) UTC during standard time.
s23.htm says in part:
*Standard time*
*2.* (1) Time in the province shall be reckoned as 3 1/2 hours
later than Greenwich mean solar time.
(2) Time reckoned in accordance with subsection (1) shall be
known as "Newfoundland Standard Time".
RSN1970 c270 s2
*Daylight time*
*3.* (1) During the period in each year that the
Lieutenant-Governor in Council may by regulation establish, time in the
province shall be reckoned as 2 1/2 hours later than Greenwich mean solar
time.
(1.1) Notwithstanding subsection (1), beginning in the year 2007
and continuing until changed under subsection (1), during the period in each
year between one minute after 12 a.m. of the second Sunday in March and one
minute after 12 a.m. of the first Sunday in November time in the province
shall be reckoned as 2 1/2 hours later than Greenwich mean solar time.
(2) Time reckoned in accordance with subsection (1) shall be
known as "Newfoundland Daylight Time".
RSN1970 c270 s3; 1987 c3 s1; 2006 c31
s1<http://www.assembly.nl.ca/Legislation/sr/Annualstatutes/2006/0631.chp.htm>
The amended section 3(1.1) reads:
(1.1) Until changed under subsection (1), during the period in each
year between 2 a.m. of the second Sunday in March and 2 a.m. of the first
Sunday in November time in the province shall be reckoned as 2 1/2 hours
later than Greenwich mean solar time.
It will be interesting working backwards to the 1970 act to see what other
changes have been made over the years, and whether the historical data is
accurate.
