According to the asia file, the Philippines jumped 24 hours on May 11, 1899, from -15:56:00 to +8:04:00 (they moved the international date line?)

Yes, they moved the date line. But this occurred in 1844, not in 1899. I think you misread the UNTIL column. zdump -i reports: TZ="Asia/Manila" - - -1556 LMT 1845-01-01 00 +0804 LMT 1899-05-10 23:56 +08 ... so the big change occurred in 1844, and the four-minute change occurred in 1899, which is what the table says.
