User account lock for 72 hours


Does any one how many login exactly is allowed in a 24 hour period.?
And Also is this 24 hour period, our Local time or Indian Standard Time or
US any time zone?

If I login at 11.50 PM , and then again next day morning 8 AM, does the login attempt get reset?

Even if I login once, but I switch to different VAC like Chennai, New Delhi , Hyderabad and check few dates within the same login, I get the “You are approaching maximum number of times error”
