    Description

      The TTLMonitor is responsible for removing expired documents from a collection with a TTL index. The expireAfterSeconds option is a numerical value that is used to calculate the expiration time for removing documents.

      Currently, the TTLMonitor ensures that this option is a numerical type but does not check for NaN or values that exceed the range of a long long type.

      To handle existing TTL indexes that may contain unrepresentable values, we should consider extracting the expireAfterSeconds option using BSON::safeNumberLong() instead. We would still be able to evaluate a reasonable expiration time from the safely converted numerical value.
