Understanding entries and timestamps in panoramic wifi gateway logs

When logged into my wifi gateway, I can see "system", "firewall", and "event" logs. My questions is regarding the firewall logs specifically.

I've noticed there is a huge difference between the "number of attempts" from one time stamp to another.

Is that determined by the length and level of activity of the user?

Also, what does the timestamp imply? Is that the time at which activity, or a certain type of activity, was ended? Or when it began? Does it represent a set time period? Should they correspond with time stamps for system and event logs?

FW.WANATTACK DROP, 3 ATTEMPTS, 2020/3/26 05:58:01     FIREWALL BLOCKED

FW.WANATTACK DROP, 432 ATTEMPTS, 2020/3/11 10:59:01  FIREWALL BLOCKED

FW.IPv6 FORWARD drop, 148 Attempts, 2020/3/17 16:58:01    FIREWALL BLOCKED

FW.IPv6 FORWARD drop, 9073 Attempts, 2020/4/14 16:58:01 FIREWALL BLOCKED

FW.IPv6 INPUT drop, 1 Attempts, 2020/3/28 12:58:01                FIREWALL BLOCKED

FW.IPv6 INPUT drop, 9467 Attempts, 2020/4/20 12:58:01          FIREWALL BLOCKED

I'm also curious what the entries mean, as in the difference between a FORWARD DROP and an INPUT DROP. But I've asked a lot already.

Thanks so much for your time!
