Getting current unixtimestamp using Moment.js

To find the Unix Timestamp in seconds:

moment().unix()

The documentation is your friend. :)

for UNIX time-stamp in milliseconds

moment().format('x') // lowerCase x

for UNIX time-stamp in seconds moment().format('X') // capital X

For anyone who finds this page looking for unix timestamp w/ milliseconds, the documentation says

moment().valueOf()

or

+moment();

you can also get it through moment().format('x') (or .format('X') [capital X] for unix seconds with decimal milliseconds), but that will give you a string. Which moment.js won't actually parse back afterwards, unless you convert/cast it back to a number first.

NOTE: This answer continues to get +1s, which is nice, but Moment has been depreciated, and alternatives like Luxon or date-fns are suggested. See: https://momentjs.com/docs/#/-project-status
