covert epoch to date string in c++?

[SelArom]

hi, I've been up and down google trying to find a function that does this. I have an integer that has the time in epoch seconds, and I would like to convert it to a string representing the date and time. is there a library with this function built in or anything that might help me do this?

thank you!

Are you talking about unix time - ie. seconds since 1970-01-01 00:00:00 UTC? If so, then you want gmtime() or localtime() which will give you a struct tm result.

yes that's what I'm talking about, but the thing is localtime wants a const time_t and the value is stored as a string. how do I pass that to the localtime function?

thank you!

At least in Gnu C time_t is just a long int. So you can just use atoi() to get from your string to an int.
