Because it's written in C, it can easily be transferred to many other languages. 7 |

 8 | To use it:
 9 | Add the 4 files to your project.
10 | Include "TimeParser.h"
11 | Then call the method parseDateTimeString(StringToParse), which returns a time_t type.  
12 | You can then turn it into struct tm * with the localtime function. 
13 |

14 | 15 | Here is what it looks like in objective c:
16 |


17 | NSString *when = @"2 days from now at 3pm";

18 | char *whenstr = (char *)[when UTF8String];

19 | time_t finalTime = parseDateTimeString(whenstr);

20 | str_time= localtime(&finalTime);

21 |

22 | 23 | To get it to work in x-code all you have to do is add the files. X code automatically generates the C files for you. 24 | 25 |
