When connecting to Adaptive Server 15.5 and later, jConnect transfers data using the bigdatetime and bigtime datatypes even if the receiving Adaptive Server columns are defined as datetime and time.
This means that Adaptive Server may silently truncate the values from jConnect to fit Adaptive Server columns. For example, a bigtime value of 23:59:59.999999 is saved as 23:59:59.996 in an Adaptive Server column with datatype time.
When connecting to Adaptive Server 15.0.x and earlier, jConnect for JDBC transfers data using the datetime and time datatypes.
