# The Investigation and Analysis Service of the

# Mexican Library of Congress (MLoC) has published a

# history of Mexican local time (in Spanish)

# http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/

# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC.

# (In all cases we go with the MLoC.)

# efecto desde las dos horas del segundo domingo de marzo y concluirá a

# las dos horas del primer domingo de noviembre.

# From Steffen Thorsen (2014-12-08), translated by Gwillim Law:

# The Mexican state of Quintana Roo will likely change to EST in 2015.

#

# http://www.unioncancun.mx/articulo/2014/12/04/medio-ambiente/congreso-aprueba-una-hora-mas-de-sol-en-qroo

# "With this change, the time conflict that has existed between the municipios

# of Quintana Roo and the municipio of Felipe Carrillo Puerto may come to an

# end. The latter declared itself in rebellion 15 years ago when a time change

# was initiated in Mexico, and since then it has refused to change its time

# zone along with the rest of the country."

#

# From Steffen Thorsen (2015-01-14), translated by Gwillim Law:

# http://sipse.com/novedades/confirman-aplicacion-de-nueva-zona-horaria-para-quintana-roo-132331.html

# "...the new time zone will come into effect at two o'clock on the first Sunday

# of February, when we will have to advance the clock one hour from its current

# time..."

#

# Also, the new zone will not use DST.
