microservices data - timestamp

Hi! I am trying to understand "timestamp" in the microservice data. The paper mentioned that these traces were collected from a 7-day period. However, the timestamp is explained in the README as "Timestamp of recorded metrics. Range from 0 to 43200000 for twelve hours (12 * 60 * 60 * 1000). The recording interval is the 30s (30 * 1000). "

Dose this mean that the timestamp only reflects the time of a given day and the exact same timestamp could mean the same time on two different days? Also, what does the recording interval mean? In the README, you mentioned two different recording interval, could you clarify which data table used which interval?

Thank you very much!

Start with the README's timestamp and recording-interval descriptions, then compare them with the referenced microservice and node data tables. Done means the README clearly explains whether timestamps span multiple days and identifies the recording interval used by each table.
