the boss respawn time is on the oblisk.ini file in secs so to set the spawn time for each one you will need to follow this formal.
60x60x(hours that you want the respawn to be)=(this is what you put on the map ini file for the mobs)
(exp ) a 12 hour spawn 12 x 60 x 60 = 43200
(exp ) a 2 day respawn 2 x 24 x 60 x 60 = 172800
i hope this has helped

[bothmob_029, (70, 1, 43200, (100,2000))] = (810.13,2.43,246.44),(2785)
map number of respawn time = exact point of spawn mobID
and sorry it was in the oblisk.ini i was working in the map ini and had that on the mind.
