In Japanese hiragana, you would say ‘1:30から3時まで中央時間’ which can be broken down into the following words in English:
- 1:30 (いちじはん, ichiji han)
- から (kara) - from
- 3時 (さんじ, sanji) - 3 o'clock
- まで (made) - to
- 中央時間 (ちゅうおうじかん, chuuou jikan) - central time
So the whole phrase in hiragana is: いちじはんからさんじまでちゅうおうじかん.
