Check if DST is set for specific date and time

i am trying to check, with plain c, whether the DST is set on a specific date and time. i have tested gmtime and localtime, but these functions only take care of the current system DST.

Thanks for your advice. thomas

Try to use zic and zdump. Use man for more information.

When I needed to know DST without holding the 6MB of compiled data I modified zic's code to create a samller table with the required data.
