Question

In Python I have this code:

now =  datetime.now().isoformat()
if "." not in now:
  now = now + ".000000"

Can I achieve the same result in Javascript?

The resulting datetime should match this mask %Y-%m-%dT%H:%M:%S.%f because the datetime will be saved into the database and then I need to retrieve it from Python code with exactly this mask.

Last example on page: https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference:Global_Objects:Date

/* use a function for the exact format desired... */
function ISODateString(d){
 function pad(n){return n<10 ? '0'+n : n}
 return d.getUTCFullYear()+'-'
  + pad(d.getUTCMonth()+1)+'-'
  + pad(d.getUTCDate())+'T'
  + pad(d.getUTCHours())+':'
  + pad(d.getUTCMinutes())+':'
  + pad(d.getUTCSeconds())+'Z'}

var d = new Date();
console.log(ISODateString(d)); // prints something like 2009-09-28T19:03:12Z
