Bidirectional to/from unix_time timestamp in PLCs

[kootzie]

I am looking for functions to/from unix_time in PLCs
so I can do time_math such as what is the time-span
between two date_times and what is the date_time of
287 hours from now

Is it as simple as generating inversions of these functions to get
from time_stamp back to YYYY-MM-DD H:MM:SS ?

oh, and examples folder is 404

Actually I'm not sure if I get your question right, sorry.
You want to get the time-span between to dates - that's actually quite simple by substract timestamp A from timestamp B and divide the result (= seconds between two datetimes) by 86400 (= 60sec/min x 60min/h x 24h/d).
Also you want the date_time of 287 hours from now which is just the current timestamp plus 287*3600 (=60sec/min x 60min/h).
I hope this is the answer to your questions, otherwise let me know.

That's actually covered in the examples (when I get your question right): /examples/convertTimestampToDate/convertTimestampToDate.ino

And

oh, and examples folder is 404

is not clear as the folder is filled with two examples (convertTimestampToDate, getTimestamps). How do you get a 404?
