I added the code to produce the DECIMAL from the TIME struct directly for DATETIME family items

Noted in 5.0.32, 5.1.14 changelogs. For a cast of a DATETIME value containing microseconds to DECIMAL, the microseconds part was truncated without generating a warning. Now the microseconds part is preserved.
