Adding a DateTime picker for date fields is an important requirement
for developing web applications nowadays. A lot of jquery plugins are available
for this. One of the most popular and easy script is here at http://trentrichardson.com/examples/timepicker/
Complete documentation, demos, formatting options etc are
also given in the above URL.
A lot of customization options are available for this plugin
and yes, the integration is very easy which we can finish within 5 minutes.
Hope this will be a great help for web developers!
