Description

nodejs/node#28635

performance became a global variable on node 16, but it does not have timing property.
and it's throwing following error.

I think this fix does not worth comments so I omitted examples and credit.

> m = require('./microtime')
[Function: microtime]
> m()
Uncaught TypeError: Cannot read properties of undefined (reading 'navigationStart')
    at microtime (.../locutus/src/php/datetime/microtime.js:17:51)

@haedaal thank you for the fix.

@kukawski When are you going to release a version with this fix?

[kukawski]

@kvz could you please handle the release? We should probably also figure out automatic publishing.

👍 + locutus@2.0.16

We should probably also figure out automatic publishing.

That would be great, as time passes my bandwidth for this project seems to decrease I'm afraid.
