Local time is the time based on the sun's position in the sky at a specific location, while standard time is a uniform time set for a region or country, often based on a central meridian. Local time varies from place to place, while standard time remains consistent within a defined area. 
 
In simpler terms:
    • Local Time:
      Think of it as the time you see based on where the sun is in the sky at that particular place. It changes as you move east or west.
  • Standard Time:
    It's a fixed time for a whole area (like a country or region). This makes it easier to coordinate schedules and activities across that area. 
     
More details: 
 
  • Local time is based on the longitude of a place. Every 15 degrees of longitude difference equals a 1-hour difference in local time. 
     
  • Standard time uses a central meridian as a reference point for a region. For example, India uses Indian Standard Time (IST), which is based on the 82.5° E longitude, according to Vedantu. 
     
  • Standard time helps avoid confusion when traveling or coordinating activities. It creates a unified time frame within a region.
