Why the timestamp returned by the CURRENT TIMESTAMP special register in DB2 for Windows have a precision of only a millisecond?

Question & Answer


Question

In DB2 UDB for Linux/Unix platforms, the "CURRENT TIMESTAMP" special register can return a timestamp with a precision of microseconds. For example, db2 "values (CURRENT TIMESTAMP)" 1 -------------------------- 2010-06-20-16.53.34.392348 However, in Windows the last 3 digits representing microseconds in the returned timestamp are always 000. db2 "values (CURRENT TIMESTAMP)" 1 -------------------------- 2010-06-20-15.42.04.578000 Therefore why in DB2 UDB for Windows platforms it can only have precision of milliseconds?
