int overflow in 3.4.1

[calvinmetcalf]

in version 3.4.1 (But not 3.4.0) I get the following warning

Warning 1: Integer overflow occured when trying to return 64bit integer. Use GetFieldAsInteger64() instead

when I have JavaScript dates like 1440518400000 represented as integers causing them to be truncated (and all the dates in my map be in the year 1970).

That looks like a bug in our code associated with GDAL 2.0 and our gdal plugin, is that what you are using?

it's reading a geojson file so maybe?

I am sorry this would be the OGR plugin.

This has been fixed in mapnik/mapnik@161469e as the bug was in mapnik-core rather then in the node bindings this will take a little while to filter its way up stream. It will be a part of the next mapnik-core release however.
