Sublime Text 2 Plugin: Timestamp for creation date and last modified date, automatically added and updated.

timestamp.py

"""
Automatically add and update time stamps in your files.
On file open, will replace [timeStamp] with the current date and time.
Currently looks for two instances of this (example below).

To use, place the text [timeStamp] in your template file where you want it.
ex.
//  CREATED: timeStamp
// MODIFIED: timeStamp

When you open this file for the first time, both [timeStamp] will change to
the current date and time. Every save, the MODIFIED line will update.

NOTE: After installing, don't open this file in Sublime Text because it will change
[timeStamp] in the code to the current time. Oops =]

			view.replace(edit, region, timestamp)
			view.end_edit (edit)

			timestamp = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
			edit = view.begin_edit()
			view.replace(edit, region, timestamp)
			view.end_edit (edit)

class UpdateTimestampListener (sublime_plugin.EventListener):
	"""
	On save, search for the MODIFIED line, and replace timestamp with current time
	"""
	def on_pre_save (self, view):
		region = view.find (TIMESTAMP_PATTERN, 1)
		if region :
			timestamp = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
			replacement = 'MODIFIED: %s' % timestamp
			edit = view.begin_edit()
			view.replace (edit, region, replacement)
			view.end_edit (edit)

Updated search string so this code will work past the year 2020 :)
