Answer:
Coded value of date 20241106 at 13300000 is: 477041750

Answer:
Decoded value of timestamp 477041750 is: 20241106 at 13300000
newdate (Fortran)
'newdate' is a Fortran function to code and decode RPN dates/times. 'newdate' is part of the RPN Fortran library. To get access to it you need to load the library 'librmn.a' when creating the executable. You can do that by added the key '-lrmn' to the compile command. For example:
