I have JSON from a service that has dates in milliseconds since epoch. For example:

{"AuthResponse":{"Token":"2ae659bb-3661-4250-ba4d-066bb814asdf3d","Expiration":1385396952932}}

But it appears that the JSON parser cannot deal with a number that large. I saw the post about using roRegEx to convert that to a string, which works just fine, but I still have no way to get a date from that string. Any ideas?

You will probably need to truncate the milliseconds, as it only deals with integer seconds for this.
value=FIX(value/1000) will do the truncation.

roDateTime makes it easy.

fromSeconds(Integer numSeconds)
• Initialize the date/time value using the number of seconds from epoch.

From your example it looks like it's using seconds since epoch already, not milliseconds as you stated -

That's a millisecond time.

The part that's missing is that can't just divide the milliseconds by 1000. The JSON/Regex conversions converts the MS to a string. You can't convert the string to an integer, it's too big. You have to convert it to a float, _then_ divide by 1000, then convert back to an int. Finally you can load the date with the now-converted-to-integer seconds.

Since you're already converting it to a string, why not just trim the last three digits off of the string before converting it back to an int?

LOL... I had not thought of that!
