Spotfire is struggling with anything below milliseconds for various reasons
Especially in the light of a streaming extension it seems a bit outdated to only support milliseconds. But even in a more classical set-up when using timestamps to identify data sets in an Oracle DB (where microseconds is very common) the millisecond limitation is a real problem for us.
Please increase supported precision for timestamps to at least microseconds, if not nanosecond which is already on the horizon e.g. with KDB+ DBs
