## Message

```
add functions to decode an epoch timestamp (#9040)

* add functions to decode an epoch timestamp

The code added here is alternative to the libc gmtime function. This function takes a unix epoch timestamp and decodes it into things like the year/day/time/etc. I looked at various libc implementations to see how it was implemented and this appears to be correct. I reorganized it so that applications can choose which data they need rather than calcualting it all in a single function. The data structures layout the order of operations required to decode various things like the year/month or time of day.

* set Month.jan to 1 instead of 0 to avoid +1 in conversion to numeric

* add another test

* remove unnecessary comptimeMod
```
