Reading the Daylight Saving Start Date and End date in linux using C/C++

[suryaemlinux]

Hi folks,
I would like to read the start date and end date of the Daylight Saving Time for the given timezone in the given year. What's the function in C/C++ to read the start of the Daylight Saving date and end of Daylight saving date?

I'm using Linux 2.6.xx Kernel.

For Example, in Pacific Time (US & Canada) the Daylight Start date for the year 2009 is Mar 9,2009 and it ended on Nov 1, 2009. I need a C/C++ function to read these dates.

Thanks in Advance,
Surya

2) need to get the following details to predict the timezone:

standard date
