Obtain current timezone in Selenium IDE using JS

I had encountered a problem in one of our projects where it was required to obtain the current time from a different timezone and then use it. I am in IST (Indian Standard Timezone - 5.50) and was required to get the time in EST (Eastern Standard Timezone + 5.00)

These are the set of commands I used to achieve that.

2Command : storeEval
3Target  : var d = new Date();
4          d.setTime(new Date( (d.getTime() + (d.getTimezoneOffset() * 60000))            + (3600000 * (-5) ) ));
5          d.toLocaleTimeString();
6Value   : timeEst
8Command : echo
9Target  : ${timeEst}
10Value   :

storeEval command is used to store the value in the variable timeEst after evaluating the javascript code.

var d = new Date(); a new date object is created.

d.getTime() method returns the number of milliseconds between midnight of January 1, 1970 and the specified date (as is present in the variable "d").

d.getTimezoneOffset() method returns the time difference between UTC (Coordinated Universal Time) time and local time from the variable "d", in minutes. For example, If our time zone is GMT-5.50, -330 will be returned.

Since getTime() is in milliseconds and getTimezoneOffset() is in minutes; getTimezoneOffset() is multiplied with 60000 to make it into milliseconds.

The expression 3600000 * (- 5) is required to make the time from UTC to EST. The difference between UTC and EST is -5 hours. So, to make the hours to milliseconds we need to multiply with 3600000 (60 min x 60 sec x 1000 millisec).

d.setTime() method is used to set the time of variable "d" after evaluating the expression.

With the above, the variable "d" is set with the date and time of the EST time.

d.toLocaleTimeString() method returns the time portion of a Date object as a string, using locale conventions.

The time string obtained above is stored in the variable timeEst.

echo ${timeEst}, the time string is displayed in the console.
