Story #63815: Reduce communication between server and client
SYS_LASTCHANGED should not change when only page permissions are changed (but it does)
There is a problem with the behavior of TYPO3 and the "access module". When admin user changes permissions for a backend group, SYS_LASTCHANGED is changed too.
So, when I use TypoScript to show last updated in frontend page, the date is updated but no content has changed.
My TS code :
lib.objPiedPage.5.30 = TEXT
lib.objPiedPage.5.30.data = page:lastUpdated
lib.objPiedPage.5.30.if.isTrue.Data = page:lastUpdated
lib.objPiedPage.5.30.strftime = %e %B %Y
lib.objPiedPage.5.30.wrap= <p> Last update: |</p>
lib.objPiedPage.5.30.data = register : SYS_LASTCHANGED

generally it would be great to be able to define what action causes an update of SYS_LASTCHANGED. For example if a new comment is posted (via frontend) I'd prefere to remain SYS_LASTCHANGED unchanged, since the article itself did not change.

No, it should change. The value is used to generate the 'Last Modified' header. If you do not change that when the content changes . . . A user with a cached version (in the browser) will check with the server when that page expires. The server will then however tell the user that the page has 'not' changed. The user will then NEVER see the new comment, perpetually serving up the content from his own cache.

I used the typoscript included to test on both 6.2.14 and 7 (latest master):
page.40 = TEXT page.40.data = page:lastUpdated page.40.if.isTrue.Data = page:lastUpdated page.40.strftime = %e %B %Y %H:%M:%S page.40.wrap= <p> Last update: |</p> page.40.data = register : SYS_LASTCHANGED page.40.if >
then I changed the permissions of one page (changed the group, or the owner, or the permissions)
TYPO3 6.2.14 > bug still present
TYPO3 7 (latest master) > bug NOT present

Not sure if it's related. I am using TYPO3 7.4.0 with the Introduction Package on a local installation with XAMPP (Windows 7 Enterprise, 64 bits):
SYS_LASTCHANGED seems to be updated only when the page (properties) itself is modified. Changing a content element does not affect the field value.

My previous test was wrongly performed, I should have used
This is the short test I performed on a new 9.5.4:
1) I used the following TypoScript:
config.no_cache=1 page=PAGE page.40 = TEXT page.40.data = page:lastUpdated page.40.if.isTrue.Data = page:lastUpdated page.40.strftime = %e %B %Y %H:%M:%S page.40.wrap= <p> Last update: |</p> page.40.data = register : SYS_LASTCHANGED page.40.if > page.100 =< styles.content.get
1) Change the permissions of the page >> the SYS_LASTCHANGED field is updated
2) Change one of the content elements on the page >> the SYS_LASTCHANGED field is not updated
