Explains booking date, value date and time zones
Booking date (when posted) vs value date (when interest applies), as in ISO 20022 camt.053; timestamps with offsets (ISO 8601).
Can AI do this?
AI does this well Most of the tested AI models master this. 3 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 96% | Not shown |
| gpt-6-luna | Low cost | 99% | Mastered |
| claude-haiku-5-5 | Low cost | 98% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: Booking date (when posted) vs value date (when interest applies), as in ISO 20022 camt.053; timestamps with offsets (ISO 8601).
How it is assessed: Answers a written question on the transaction dates and times correctly
