MaxCreatedAt limit config not updating after relay start

[UTXOnly]

What happened

Receiving error below when adding events from a timestamp that should be within the allowed timestamp range:

["OK","1fa30db9ed533b4e5934e6f0809f3d8952611db0b8b1acd5838a552894768b40",false,"invalid: event created_at timestamp is out of allowed range"]

Steps to reproduce

• Start GRAIN relay
• Immediately post an EVENT
  • EVENT is accepted
• Wait 5+ minutes, post another EVENT
• EVENT is rejected due to created_at timestamp out of allowed range

Example

Observations

It looks like the function below is setting the value of cfg.EventTimeConstraints.MaxCreatedAt to 5 minutes ahead of now.Unix() but that value is stuck at 5 minutes ahead of the relay start time.

    // Adjust max_created_at based on string value or default to current time
    if strings.HasPrefix(cfg.EventTimeConstraints.MaxCreatedAtString, "now") {
        offset := strings.TrimPrefix(cfg.EventTimeConstraints.MaxCreatedAtString, "now")
        fmt.Printf("Offset is: %s", offset)
        duration, err := time.ParseDuration(offset)
        if err != nil {
            fmt.Printf("Invalid time offset for max_created_at: %s\n", offset)
            cfg.EventTimeConstraints.MaxCreatedAt = now.Unix() // Default to now if parsing fails
        } else {
            cfg.EventTimeConstraints.MaxCreatedAt = now.Add(duration).Unix()
        }
    } else if cfg.EventTimeConstraints.MaxCreatedAt == 0 {
        // Default to the current time if it's set to zero and no "now" keyword is used
        cfg.EventTimeConstraints.MaxCreatedAt = now.Unix()
    }
}
