Say you're working on a big project. Then at some point you call strftime or maybe ctime and what do you get but a nasty and mysterious SEGFAULT?? What's more you are absolutely sure you have no memory leaks, nothing is wrong with the arguments to the call. Then gdb tells you only that the segfault is happening somewhere deep inside the library call. Furthermore, it works on some platforms but not others, indicating again that memory leak you are sure you don't have. So what do you do but spend three hours tracking down your much doubted memory leak? Well hopefully you find this very post and save those three hours. You see, if time.h is included in another source file, you may have forgotten to include it where you use it. The compiler won't blink an eye. The linker doesn't even complain. Yet somehow it all works dandy until you try it on the TA's computer. So long story short, check your includes.
