[tz] Inquiry to NICT about Japanese Summer time in 1948-1952.

To receivers of this email: Recently, I have read an article, which mentioned the history of Japanese Summer Time Implementation in the past at www.bengo4.com/internet/n_8461/ . In the article, it was mentioned that the summer time (DST) end at 25 hours at the last day of the implementation period. Does that mean the clock would go up to the 25th hours back then and reach 24:59 before it continues toward 00:00 on the next day in standard time? If not then how did the clock switched from Summer Time back to Standard Time back then? Please use the "reply to all" function when replying to the message so that other receivers of the message can also hear answer on the matter. Sincerely, P.N.
