Indian Railways to telcos, everyone must follow this specific time; see what is in store on Indian Standard Time
Legalising IST is a way to legally synchronise the time of the country. This means a single time regulated by National Physical Laboratory (NPL) will be followed across the country at all places may it be Indian Railways or telecom networks. To access this service, each and every service provider of the country will have to approach the National Physical Laboratory (NPL), the official timekeeper of the nation, and seek a time set by it
The Indian Railways Disaster Management Department is expected to approach the laboratory for setting a standard time for itself and its customers. Image source: Reuters
