Error

Am having another doubt:
If we go through Management->Index Patterns->Select the Index pattern needed->timestamp->editing the timestamp->Format ->{its currently set to default)but if we change it to date,we can see another box down to the format where there is some kind of format displayed saying moment.js format pattern (Default: "MMMM Do YYYY, HH:mm:ss.SSS") .Down to that a box is provided, so can i do any kind of editing there?
Will it work?
Do reply
