In 1999, the change to 60364499Swollman# daylight savings time was still on a Friday morning but from 60443543Swollman# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time 60564499Swollman# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for 60664499Swollman# 1999 only.
