Scheduling between the two
Working hours overlap from 9:00 am to 2:00 pm WAT, which is 1:30 pm to 6:30 pm IST. Anything inside that window falls in the normal working day at both ends.
A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.
West Africa Time (WAT) is used in Nigeria, Algeria, Angola and Cameroon
India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving
