According to the valadoc
var now = new DateTime.now(new TimeZone.local());
var timestamp = now.format("\%F.\%T");
should set timestamp to “2012-08-28.09:51:06.” Why “error: invalid escape sequence” on “F” and “T?” Other formats from the valadoc cause the same error and now.to_string() is in fact “2012-08-28T09:51:06+0000”
Edit: Perhaps embedded-linux target is missing something?
Edit: The test code here prints “(null)” in this project which uses glib 2.26.1.
As NullUserException mentioned, you shouldn’t be including the backslashes–that is what is causing the invalid escape sequence error.
The reason it still doesn’t work after removing the backslashes is that the %T format specifier wasn’t added until the 2.30 cycle. The relevant commit is 414c8ce532c19fe65deb8dfb80222d0164be5cbe
You can work around it by doing something like this instead:
