Trying to filter events by date

hi! i’m trying to get all events created after some date in my workspace. i don’t think there’s a way to explicitly do this, so i’m trying to figure out if there’s a way to figure out which contacts have associated events created after some date

first i tried to filter using ‘last_seen_at’ but then i realized some contacts have an old ‘last_seen_at’ value but newer events. now i’m looking at ‘updated_at’ and it looks like it might work

so the question i have is whether ‘updated_at’ for some contact gets updated when there’s a new event associated to this contact. thanks!

also i just found another issue while trying to filter contacts using update_at: i’m sending this query to the API {'query': {'field': 'updated_at', 'operator': '>', 'value': 1585699200}, 'sort': {'field': 'updated_at', 'order': 'ascending'}, 'pagination': {'per_page': 150}} (1585699200 is timestamp for 2020-04-01 00:00 UTC` and i get the following values for updated_at: 2020-04-02 04:00:16, 2020-04-02 04:00:16, 2020-04-02 04:09:48, 2020-04-02 04:39:01…

it looks to me like it’s giving me dates that are 28 hours ahead from where i’m expecting it them to start (which is 2020-04-00 00:00:00 UTC) . am i doing something really wrong here?
