Duration along the local timescale AMERICA_NEW_YORK
A - the last nanosec of the day BEFORE the 1972 leap-second day - 1972-06-29 (not the 30th), NEW YORK
B - the first nanosec (not zeroth) of the day AFTER the 1972 leap-second day (1972-07-01), NEW YORK
C - Duration: it has found the intervening leap-second (day length = 86401)

=====================================
Duration between two local timescales, EUROPE_LONDON and AMERICA_NEW_YORK
Note EUROPE_LONDON is DST wintertime and AMERICA_NEW_YORK is DST summertime

Start with second before Daylight Onset 2017-03-26 EUROPE_LONDON
D2017-03-26T00:59:59n000000000U+00Zeurope/londonAgmtV2021aL27S00t01a01cMmX

Convert EUROPE_LONDON to AMERICA_NEW_YORK Zone
This yields the same instant in EUROPE_LONDON and AMERICA_NEW_YORK
Note EUROPE_LONDON is wintertime, AMERICA_NEW_YORK is summertime

D2017-03-25T20:59:59n000000000U-04Zamerica/new_yorkAedtV2021aL27S01cMmX

Add AMERICA_NEW_YORK UTCOffset (UTC-05:00) to AMERICA_NEW_YORK
This shifts the AMERICA_NEW_YORK time
Thus the YMDhms is -05:00 behind EUROPE_LONDON

A - second before Daylight Onset 2017-03-26 EUROPE_LONDON
B - 5 hours later (UTC-05:00) than A in AMERICA_NEW_YORK
C - Duration: the diffrence is the zone offset (UTC-05:00)

Add one second to A and B
Note EUROPE_LONDON is now summertime, AMERICA_NEW_YORK is summertime
A - Second of Daylight Onset in EUROPE_LONDON
B - 5 hours later (UTC-05:00) than A in AMERICA_NEW_YORK
C - Duration: the diffrence is the zone offset (UTC-05:00)
