How echo a datetime in “YYYY-MM-DD” format in linux and powershell with a same command?

Question

I do have a php 'composer' command which generates a .zip package for deploy.

this package should have the datetime as sufix, for instance release-2018-09-12 or release-2018091 .

However some of our programmers and freelancers use both windows and Linux.

The date +%Y-%m-%d only works on Linux. but not on windows.

How can I write a command that works both in Linux or windows (powershell)? or a workaround to it?

Get-Date的“ -UFormat”开关代表“ Unix格式”

Get-Date -Uformat "%Y-%m-%d"
