Too Much Request Error

I’m trying to record the price of a stock per second. Then I get a too much request error. I know the limit is 200 request per min. Is there a daily limit?

I also notice a discrepency on time.

Code:
ZonedDateTime local = ZonedDateTime.now(ZoneId.of(“America/New_York”));
ZonedDateTime server = api.getClock().getTimestamp();

Output:
|Local:|2020-04-28T14:26:05.332761300-04:00[America/New_York]|
|Server:|2020-04-28T14:26:06.048279727-04:00|

Is this normal? I don’t want to request clock every second because that count as one request, right?

Thanks
