The tz-database says UT-12 until 1993 Aug. 20, UT+12 since then, with a little complication for the period Oct. 1969 - Aug. 20 1993.
As far as I know, that complication applies only to Kwajalein, and the rest of the Marshall Islands have been at UTC+12 since October 1969.
You're right I guess. So, since Oct. 1969 the Marshall Islands are on UT+12, except for Kwajalein, which was on UT-12 until Aug. 20 1993. It is probably safe to say that Enewetak was since Oct. 1969 on UT+12. The Kwajalein exception is probably due to the fact that the US military base on Kwajalein preferred a more manageable time scheme. Oscar van Vlijmen 2003-09-20
