问题
I want to create a snippet that will add a file comment, but I want the snippet to create the DateTime automatically. Can a sublime snippet do that?
<snippet>
<content><![CDATA[
/**
* Author: $1
* DateTime: $2
* Description: $3
*/
]]></content>
<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
<tabTrigger>/header</tabTrigger>
<!-- Optional: Set a scope to limit where the snippet will trigger -->
<scope>source.css,source.js,source.php</scope>
</snippet>

Tools > New Plugin
Paste this:
import datetime, getpass
import sublime, sublime_plugin
class AddDateCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("insert_snippet", { "contents": "%s" % datetime.date.today().strftime("%d %B %Y (%A)") } )
class AddTimeCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("insert_snippet", { "contents": "%s" % datetime.datetime.now().strftime("%H:%M") } )
Save it as ~/Library/Application Support/Sublime Text 2/Packages/User/add_date.py
Then, in Preferences > Key Bindings - User , add:
{"keys": ["ctrl+shift+,"], "command": "add_date" },
{"keys": ["ctrl+shift+."], "command": "add_time" },
You can customize the argument passed to strftime to your liking.

Nachocab, that was a GREAT answer - and helped me VERY much. I created a slightly different version for myself
~/Library/Application Support/Sublime Text 2/Packages/User/datetimestamp.py:
import datetime, getpass
import sublime, sublime_plugin
class AddDateTimeStampCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("insert_snippet", { "contents": "%s" % datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S") } )
class AddDateStampCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("insert_snippet", { "contents": "%s" % datetime.datetime.now().strftime("%Y-%m-%d") } )
class AddTimeStampCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.run_command("insert_snippet", { "contents": "%s" % datetime.datetime.now().strftime("%H:%M:%S") } )
Preferences > Key Bindings - User:
{"keys": ["super+alt+ctrl+d"], "command": "add_date_time_stamp" },
{"keys": ["super+alt+d"], "command": "add_date_stamp" },
{"keys": ["super+alt+t"], "command": "add_time_stamp" }
I wouldn't have been able to do this without your help! I scoured google for about an hour now and finally was graced by your answer! Thank's so much!

You might want to check the InsertDate package: https://github.com/FichteFoll/InsertDate
In the readme you can find an example of how you can use macros to insert timestamps into snippets.
回答4:
You can use the SMART Snippets plugin for Sublime Text 2.
With SMART Snippets, You can now use Python to dynamically create snippets
I did some research for another question and I am pretty sure this plugin could solve your question.

I just implement this function (on sublime3) by a simple plugin and the metadata file (.tmPreference file), but I don't know whether this is efficient. There is the way,
1. create a .tmPreference file, put some variables you want to use in snippets. There is an example, you can save the cotent in Packages/User/Default.tmPreference
<plist version="1.0">
<dict>
<key>name</key>
<string>Global</string>
<key>scope</key>
<string />
<key>settings</key>
<dict>
<key>shellVariables</key>
<array>
<dict>
<key>name</key>
<string>TM_YEAR</string>
<key>value</key>
<string>2019</string>
</dict>
<dict>
<key>name</key>
<string>TM_DATE</string>
<key>value</key>
<string>2019-06-15</string>
</dict>
<dict>
<key>name</key>
<string>TM_TIME</string>
<key>value</key>
<string>22:51:16</string>
</dict>
</array>
</dict>
</dict>
</plist>
2. create a plugin, which will update the shell variables in .tmPreference file when the plugin loaded.
import sublime, sublime_plugin
import time
from xml.etree import ElementTree as ET
# everytime when plugin loaded, it will update the .tmPreferences file.
def plugin_loaded():
# res = sublime.load_resource('Packages/User/Default.tmPreferences')
# root = ET.fromstring(res)
meta_info = sublime.packages_path() + '\\User\\Default.tmPreferences'
tree = ET.parse(meta_info)
eles = tree.getroot().find('dict').find('dict').find('array').findall('dict')
y = time.strftime("%Y", time.localtime())
d = time.strftime("%Y-%m-%d", time.localtime())
t = time.strftime("%H:%M:%S", time.localtime())
for ele in eles:
kvs = ele.getchildren()
if kvs[1].text == 'TM_YEAR':
if kvs[3].text != y:
kvs[3].text = y
continue
elif kvs[1].text == 'TM_DATE':
if kvs[3].text != d:
kvs[3].text = d
continue
elif kvs[1].text == 'TM_TIME':
if kvs[3].text != t:
kvs[3].text = t
continue
tree.write(meta_info)
3. use the shell variable you defined in .tmPreference file.
<snippet>
<content><![CDATA[
/**
******************************************************************************
* \brief ${1:}
* \file $TM_FILENAME
* \date $TM_DATE
* \details
******************************************************************************
*/
${0:}
/****************************** Copy right $TM_YEAR *******************************/
]]></content>
<!-- Optional: Tab trigger to activate the snippet -->
<tabTrigger>cfc</tabTrigger>
<!-- Optional: Scope the tab trigger will be active in -->
<scope>source.c, source.c++</scope>
<!-- Optional: Description to show in the menu -->
<description>c file comment</description>
</snippet>

It solved in https://github.com/ngocjr7/sublime-snippet-timestamp
Copy all file to Packages/User directory of sublime text.
Configure sublime-snippet file as you want ( cpp_template.sublime-snippet for c++ and py_template.sublime-snippet for python)
Now you can create a simple snippet and the date will be updated every time you press command + s. command + s still has the function to save files.
Explaination
Because snippet doesnot support dynamic variable, I use static variable DATE define in Default.tmPreferences and update this variable when we want to create snippet.
I use a plugin (command) updatetm to update DATE in Default.tmPreferences.
I want the date and time to be updated automatically or at least passive. So I added a function that called updatetm command for keystrockes command + s. To do this, I use another plugin is chain.py to call multiple command on a keymap (both updatetm command and the default command (save). Keymap defined in Default (OSX).sublime-snippet file.

This post on the official ST forum answers your question and provides a close alternative.
In summary, no, you cannot currently insert datetime from a ST snippet.
