Follow-up Comment #22:

Here is one case that breaks the approach in this patch:


>> getenv TZ
ans = America/Caracas
>> datevec ('2016-05-01 02:25:00')
ans =

   2016      5      1      2     25      0

>> datevec ('2016-05-01 02:30:00')
ans =

   2016      5      1      3      0      0

>> datevec ('2016-05-01 02:40:00')
ans =

   2016      5      1      3     10      0



Here is another case


>> getenv TZ
ans = Australia/LHI
>> datevec ('2017-10-01 01:50:00')
ans =

   2017     10      1      1     50      0

>> datevec ('2017-10-01 02:00:00')
ans =

   2017     10      1      2     30      0

>> datevec ('2017-10-01 02:10:00')
ans =

   2017     10      1      2     40      0

>> datevec ('2017-10-01 02:20:00')
ans =

   2017     10      1      2     50      0

>> datevec ('2017-10-01 02:30:00')
ans =

   2017     10      1      2     30      0
