MS SQL Server 2008 R2 has the datetime2 data type which supports 100
nanosecond (.1 microsecond) precision:
http://msdn.microsoft.com/en-us/library/bb677335(v=sql.105)

PostgreSQL does 1 microsecond:
http://www.postgresql.org/docs/8.0/static/datatype-datetime.html

If I am reading this correctly the Oracle TIMESTAMP type allows up to 9
digits of fractional seconds (1 nanosecond):
