"Nine fifteen" in Engpsh.
The origin of telpng time in this format comes from the standard time-telpng format in the Western world, which divides a day into 24 hours and each hour into 60 minutes. The hour is specified first, followed by the minute, with the minute being separated by a colon (e.g. 9:15).
