I have a timestamp object that looks like this: timestamp = 1430770060000. I want to remove the last 3 numbers which represent miliseconds. Since it is a date object, I can't find a method to remove the miliseconds. I tried to convert the value to a string and then use the slice(0,3) to remove the last 3 numbers and convert the remaining 10 characters back to a date, but had an issue. Can someone please help me understand how I can remove the miliseconds from the date.
 
Have you tried the divide and conquer approach.

Math.floor(timestamp / 100)

Dividing by 100 would move only get rid of the last 2 digits.

As the JavaScript [tt]Date[/tt] objects internally handles dates as milliseconds, you have to use it as is. Rounding it to seconds results a different value so for the [tt]Date[/tt] object a different date.

If is really important for compatibility with other languages' date handling, your best option is to make your own functions to do the handling as you want, maybe as methods of the [tt]Date[/tt] prototype :
JavaScript:
[gray]// declare them[/gray]
Date[teal].[/teal][b]prototype[/b][teal].[/teal]getUnixTime [teal]=[/teal] [b]function[/b][teal]() {[/teal] [b]return[/b] Math[teal].[/teal][COLOR=orange]floor[/color][teal]([/teal][b]this[/b][teal].[/teal][COLOR=orange]getTime[/color][teal]() /[/teal] [purple]1000[/purple][teal]) }[/teal]
Date[teal].[/teal][b]prototype[/b][teal].[/teal]setUnixTime [teal]=[/teal] [b]function[/b][teal]([/teal]time[teal]) {[/teal] [b]return this[/b][teal].[/teal][COLOR=orange]setTime[/color][teal]([/teal]time [teal]*[/teal] [purple]1000[/purple][teal]) }[/teal]

[gray]// use them[/gray]
[b]var[/b] sometime [teal]=[/teal] [b]new[/b] [COLOR=orange]Date[/color][teal]()[/teal]
sometime[teal].[/teal][COLOR=orange]setUnixTime[/color][teal]()[/teal]
console[teal].[/teal][COLOR=orange]log[/color][teal]([/teal]sometime[teal].[/teal][COLOR=orange]getUnixTime[/color][teal]())[/teal]
