Legalizing IST will streamline, cut down confusions and the risk of errors in several key operations.
For instance, if a customer is booking a train ticket in Tatkal and is using network time but the Indian Railways is operating on IST sourced from NPL, he might see no tickets on logging in, courtesy the lack of coordination in the two times.
"When it comes to security, including defense and cyber security, ATM and online transactions, even seconds make a difference. We are pushing for nation, one time, so there's only one source of Indian Standard Time," Ashish Agarwal, a scientist at NPL, said.
As of now, only key organizations including the ISRO, the Indian Air Force, airports and several banks use NPL-generated IST.
