How to get Date in java.util.Date instead of Unix Timestamp in bash script?

I have an .sh script on my Linux server.

I need the date in milliseconds in Java, but everything I find on the net is giving me Unix Timestamp.

Like this: date=$(date -d 'today 00:00:00' "+%s")

I need java milliseconds, like here: https://www.fileformat.info/tip/java/date2millis.htm.

How do I get that easily without writing a long java code? There has to be an easy solution.

It's just unix epoch in milliseconds instead of seconds, so simply replace +%s with +%s%3N.\nepoch_milli=$( date -d 'today 00:00:00' +%s%3N )\n\n$ date +%s; date +%s%3N\n1666798614\n1666798614357\n\nConversion using your site",
