Update time zone of the United States-Mexico border

[Obed Javier]

Hello, I use the google translator, so I apologize if there is a misspelled word, the clock of ubuntu do not display correctly when my city, I wrote my question ( https://answers.launchpad.net/ubuntu/+question/104324 ) and I was advised to write to the website of tzdata.
They told me they have everything in order, so I make my report here.

Basically, the problem is that in my city (Matamoros, Tamaulipas, Mexico) and entered the summer time (like other border cities, with the U.S.), but the clock does not show me this change, continues with DST the rest of the country.
In border cities, daylight saving begins second Sunday in March at 2 am, while in the rest of the country, remains unchanged (on 4 April or the first Sunday in April). As a reference, I put the link of the news:

Finally, I attach the screenshot of the hour, my city and the neighboring city (Brownsville, Texas), both cities should have the same time, however, on my sample backward.

Original text in Spanish

Hola, uso el traductor de google, asi que disculpen si hay una palabra mal escrita; el reloj de ubuntu no me muestra correctamente la hora de mi ciudad, ya escribí mi pregunta ( https://answers.launchpad.net/ubuntu/+question/104324 ) y me recomendaron escribir a la web de tzdata.
Ellos me respondieron que tienen todo en orden, asi que hago mi reporte aquí.

Básicamente, el problema es que en mi ciudad (matamoros, tamaulipas, mexico) ya entro el horario de verano (al igual que otras ciudades fronterizas, con estados unidos), pero el reloj no me muestra ese cambio, sigue con el horario de verano del resto del país.
En las ciudades fronterizas, el horario de verano inicia el segundo domingo de marzo, a las 2 am, y en resto del país, sigue sin cambios (el 4 de abril o primer domingo de abril). A manera de referencia, pongo el link de la noticia:

Finalmente, adjunto el screenshot de la hora, de mi ciudad y la ciudad vecina (brownsville, texas), ambas ciudades deben de tener la misma hora, sin embargo, en la mía la muestra atrasada.

After an update, there's a new time zone, my city, Matamoros.
But if I choose locations (climate), matamoros, returns to the zone for the rest of the country, ie 1 hours back the clock enters the zone of america / mexico city instead of that in the update, america / matamoros.
I appreciate the progress of the new time zone, but could fix that last little detail?

Since the issue of this report was fixed according to last message from original reporter I have marked as Fixed. Please if your second problem is still occurring could you fill a new report about it? Thanks.
