Change in Mongolian daylight saving time

[Ganbold]

Hello,

Current rule settings for Mongolia in /usr/src/share/zoneinfo/asia is wrong.

It should be changed from:
...
Rule    Mongol  2001    only    -       Apr     27      2:00s   1:00    S
Rule    Mongol  2001    only    -       Sep     28      2:00s   0       -
...

To the following:
...
Rule    Mongol  2001    only    -       Mar     lastSat      2:00s   1:00    S
Rule    Mongol  2001    only    -       Sep     lastSat      2:00s   0       -
...

Daylight saving occurs at 02:00 local time last Saturday of March.
It will changes back to normal at 02:00 local time last Saturday of September.
Please make appropriate changes.

Please let me know if you have any questions.

sincerely,

Ganbold Ts.
Mongolia
