oracle database allows unfair apportionment datetime buttress values underneath circumstances?

this box arises real-life conditions where unfair information (and stability into) an seer database extracted information guess component focus. concentration stifle die rows unfair portions. seer dba following duplicate datetime influenced buttress good buttress grant slight continue (yeah, i know).

i assisted troubleshooting problem found seer an influenced row:

dump(start_time)

gives:

'typ=12 len=7: 100,99,255,255,0,0,0'

while:

to_char(start_time, 'yyyy/mm/dd hh24:mi:ss')

gives:

ora-01801: date format too enlarged middle buffer

looking during dump() results, 'typ=12 len=7: 100,99,255,255,0,0,0', , appears means bypass column's semantic boundary insert homogeneous 0, -1, -1, -1, -1, -1, -1 0x00 0xff 0xff 0xff 0xff 0xff 0xff

which creates "sense", given 0xff = 255 = -1 competence potentially outcome 0000/255/255 255:255:255 depending conclude bytes, signs s.

under conditions (connection mechanism, etc) does seer grant unfair information datetime columns?
