Time

I was trying to put together a program recently that would create a txt log file each time a user created a log entry it would time stamp the entry.

Now my question is is there an eazier way to get the current time so you can put it into a string other then using the time.h file or if you do what would be the correct way to obtain the time in this kinda format --> 8:45pm or possibly military time.

I know this can be diffrent on difrent operating systems so im trying to keep as general as poosilble with the answers.

did you try the "date" command?

if you want it 8:45pm, it's [date "+%I:%M%P"], everything in the brackets.

if you want it 8:45PM, it uses a lowercase %p, date --help should show you.

Sorry mabye i should have clarifyed this is for C: programming not bash

I could however use the date command in the program but was really looking for something more in a .h file or something. Mabye i should take a look at date's source file.

Why did you not want to use time.h ?

I would offer time(), and ctime_r() - where ctime_r produces a string like this "Wed Jun 30 21:49:08 1993\n" - notice it includes a newline char at the end.

For portability the GLib library also has a collection of time and date functions that are portable across most nix systems and windoz.
