Question

In a javascript function how do I add two time values together, for example it needs to be able to add 25 hours and 3 days together. It can be called for instance by: timeAdder(5,"days",25,"hours")

Answer 1

Depending on the format of the output:
You can convert everything into the smallest unit of time (you will get 25+72 =97 hours
.. or use modulo operator to get back to day+hours eg "4 days and 1hour".
