UTC falls back at a leap second. Nope. There is no fall back for leap seconds. They are *inserted* into the time stream (Temporal Mechanics 101). When that happens, UTC goes from 11:59:59 to 11:59:60 to 00:00:00. It doesn't pause, repeat, or go backwards. How an OS translates that concept into its local clock is left an exercise to the vendor.bbbbbbbbbbbb Alan Altmark IBM ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
