International Standard Business Time is a "time zone" that does not change based on location. This time is the same throughout the planet. If it is 10:00 IBST in Moscow, it is also 10:00 IBST in Texas. IBST allows international companies to sync with each other. It is most commonly seen in the 24hr format- I.e. 00:00 is midnight. IBST is the same as GMT, but as earlier stated, is recognized globally and does not depend on location.
We've set a meeting with all the GMs via Skype conference for July 11th at 1300 International Business Standard Time (IBST).
