Call For Papers


****** 28th International Symposium on Temporal Representation and Reasoning ******

Klagenfurt, Austria, 27-29 September 2021,



- Since 1994, the TIME International Symposium on Temporal Representation and Reasoning aims to bring together researchers in the area of temporal representation and reasoning in different areas of Computer Science and related disciplines.

- TIME 2021 will be organized as a combination of technical paper presentations, keynote talks, and tutorials.
Besides sustaining the traditional three tracks (Time in Artifical Intelligence, Temporal Databases, and Temporal Logic and Reasoning) TIME 2021 in particular wants to stimulate cross cutting concerns.

- TIME 2021 will be a hybrid conference. We are planning to have virtual participation for delegates and online presentations. We will also try to allow also an in-presence participation, according to the rapidly evolving pandemic situation.


- Time in Artificial Intelligence
- Temporal Databases
- Temporal Logic and Reasoning


- Temporal representation and reasoning for Covid-19
we are looking for submissions dealing with temporal issues in any context having to manage Covid-19 pandemic (healthcare, medicine, social contexts, school, and so on)
- Temporal explainability: connecting symbolic and sub-symbolic temporalities
we are looking for submissions dealing with some kind of temporal logics/system/rules/visualization for interpreting/explaining the results of machine learning algorithms considering temporally relevant problems.


As in recent years, we plan to invite authors of selected papers to submit an extended version of their contribution to a special issue of the journal Information and Computation (to be confirmed) and in addition selected papers of the special track will be invited to a special issue on Temporal representation and reasoning for Covid-19 in the journal Artificial Intelligence in Medicine.


TIME 2021 accepts submissions in PDF format, no longer than 12 pages excluding references and appendix. The appendix is limited to 5 pages, and the reviewers may or may not take it into account for their recommendation. Submissions must be formatted following the LIPIcs instructions (, and preferably redacted in LaTex. All submissions have to be made electronically via easychair at (details at

Important Dates

- Papers and abstract due: May 24, 2021
- Notification: June 23, 2021
- Final camera-ready version: July 7, 2021
- Conference: September 27-29, 2021
TIME policy is single-blind, so the names of the authors need not be hidden in the submitted draft. Members of the program committee, excluding the PC chairs, are allowed to submit papers. Submitted papers will be refereed for quality, correctness, originality, and relevance to the conference.

Submissions to TIME 2021 must be original, parallel submissions of the same material to other conferences or journals are not allowed. Accepted papers will be presented at the symposium and included in the proceedings, which will be published by LIPIcs-Leibniz International Proceedings in Informatics (, a series of high-quality peer-reviewed conference proceedings which are published according to the principle of OpenAccess. At least one author of each accepted paper must register at the conference and present either virtually or (if possible) in person. In-person participation in the symposium will not be a prerequisite for publication.
