When writing answers to questions, I sometimes would like to add remarks that get removed or replaced by other remarks automatically after a day or two.

For example with one answer I wished to point out that I just submitted a package to CTAN which should be available via CTAN in a day or two.
After a day or two that remark should be changed to pointing out that there is a package available at CTAN.

Is automatizing such things possible via the web interface of StackExchange or will I have to wait for two days and then log in at StackExchange and edit my answer "by hand"?

By 'remarks' you might mean either part of the text of an answer or a comment on an answer. In either case the answer is 'no, there is no automation' but the reasoning is I suppose slightly different. For answers, they are explicitly supposed to be written by someone as dealing with the matter raised in a question. As such, they are quite deliberately never auto-changed. Comments are intended as not the answer: they are not searchable, etc. There have been questions in various places about some 'auto-cleanup' of comments (which would leave answers unchanged), but this has never been agreed by the network. (Various arguments have been put forward on both sides, from memory.)
