I achieved it using mktime, again using your examples above, to ensure the hours remained between 0 and 23 (inclusive).ĭespite this, i am really very grateful. If i may criticise one point – your timezones example has the potential to go over midnight, and even negative. And some contain examples that don’t even work! Many thanks for this!

admin on June 29th, all depends what you are trying to do.

I would like to measure 24 hrs on my machine without waiting for 24 hrs…… is it possible ? (By making some useless calculation in loop). I was going through your site and found it quite interesting. I was reading your blog and thought i would say hi. If I have some time tomorrow I will post a example.Īs promised in the previous comment, we have created a calendar tutorial that you can find here. The best thing you can do is to create a calendar function for yourself. The leap year calculation can be done like so: However, if the year is also divisible by 400, then it is a leap year. If a year is divisible by 4, then it is a leap year, but if that year is divisible by 100, then it is not a leap year. Note: a leap year does not strictly fall on every fourth year.

You also have to make sure it’s not a leap year (see note.) So your calculation get harder. The hard answer is: you have to take the number of days of the month your into account. If this is your question, then the simple answer is +1. Hope it answers your question.ĭon’t exactly know what your question is, but I think your question is: you have a current date.

I don’t know exactly what your question is but the function time() can be used if you include time.h on Unix systems and the function will return the type time_t.
