If datetime - epoch() >= DatetimeInterval(), load into the specified result the relative time converted to a bsls::TimeInterval, computed as the difference between the specified absolute datetime and the epoch, and return 0. Otherwise, return a non-zero value (with no effect on result).

DEPRECATED: Use convertToTimeInterval(datetime) instead.
