Their names all start with double underscores. __DATE__ This macro expands to a string constant that describes the date on which the preprocessor is being run. The string constant contains eleven characters and looks like "Feb 12 1996". __TIME__ This macro expands to a string constant that describes the time at which the preprocessor is being run. The string constant contains eight characters and looks like "23:59:01". read less

_DATE_ & _TIME_ are macros designed and defined to display the date & time on which the preprocessor is being run. DATE will be in Month Date and Year ie Jan 20 2015 (11 characters) and TIME will be in Hours Minutes & seconds i.e. 18:40:10 (8 characters)

They will put in Current Date and Time (at the time of compiling (pre-processing to be precise)). Please remember that this date, time becomes hardcoded like a string literal. So it will only give you date and time of pre processing and not the date and time of execution. example: #include stdio.h...
