Showing Dates / Timestamps for log entries

[bennycode]

I really like the logdown.js project but does it support timestamps in front of log messages?

We are looking for something that can replace our current log library which gives us these features:

For timestamps in Chrome you can use this checkbox:

But that would work only in Chrome, not in other browsers or Node.js
We can implement this
Seems to be easy and straight forward

I'm thinking in an API similar to

// Prints timestamp in the format `2016-08-13` or `YYYY-MM-DD`
const logger1 = new Logdown({
  prefix: 'lorem',
  timestamp: true
})

// If a string is passed, we use it as a template for formatting the timestamp
const logger2 = new Logdown({
  prefix: 'lorem',
  timestamp: 'MM/DD/YYYY'
})

// Throws an error in case we can't parse the string passed as template
const logger3 = new Logdown({
  prefix: 'lorem',
  timestamp: 'ipsum'
})

Thoughts?

From the first view, I like having a date format like 'MM/DD/YYYY'. One option I thought of is that prefix could accept also functions. Then people could write their own date mechanism, like:

const logger = new Logdown({
  prefix: function() {
    var time = new Date().toLocaleString();
    return time + ' MyModule';
  }
});

Like both ideas

1. prefix should accept a function
2. Output timestamp behind a flag

You mind crating issues for both so we can work on it?

I created the two issues:

1. Allow function value for "prefix" property #48
2. Support "timestamp" property #49

From my side we can close down this issue here. WDYT?
