Yes, Indonesia introduced three time zones:  Waktu Indonesia Barat,
Waktu Indonesia Tengah, and Waktu Indonesia Timur on from 1964
(President decree number 243 year 1963).

Before 1964,  Indonesia used six time zones (President decree number
152 year 1950):  Waktu Irian (GMT+9), Waktu Maluku (GMT+8:30), Waktu
Sulawesi/Celebes (GMT+8), Waktu Jawa (GMT+7:30), Waktu Sumatera
Selatan (GMT+7), and Waktu Sumatera Utara (GMT+6:30).

I tend to agree with you however I don't have formal documents
(president decree year 1950 and year 1963) in my hand.
Thus, I don't have legal reason for proposing tzdb abbreviation changes.

Best Regards,

1.I sent email to several ministry offices asking for president decree
1950 and 1963. so far no reply.
2.I will try to phone next week.
