how to convert the waves timestamp

[arnezt]

I am still not get the date format for waves timestamp more than 10 digits, something like this: 1561174381555 as I know In PHP date format just 10 digits. I have try to use:
date('Y-m-d H:i:s T') but the output: 51441-08-25 05:25:55 WIB
but if I substr 3 digit from behind 1561174381(555) the output: 2019-06-22 10:33:01 WIB
what is the actual date format for waves timestamp?
Thank you.

• waves timestamp in milliseconds
• php date timestamp in seconds
• divide waves timestamp by 1000 (or do substr, as you wish)

Thank you very much for your response. I will use the first option that divided by 1000
