Questions
What time is 3 PM CET in IST?
3:00 PM Central European Time is 6:30 PM India Standard Time in northern summer and 7:30 PM in winter, because only one side changes its clocks, or they change on different dates.
Is CET the same as Central European Time?
Not always. Central European Time (Berlin, Paris, Madrid, Rome) is CET (UTC+1) in winter and CEST (UTC+2) from late March to late October. This page uses Central European Time as Berlin lives it, and says which one applies on the date you pick; choose "CET, fixed UTC+1" to use the fixed offset instead.
Does IST change for daylight saving?
IST here is India Standard Time (UTC+5:30), which has no daylight saving. Not Irish or Israel Standard Time.
