I agree with @joelbladen and @wizprod. All the logs are recorded in GPST. I’m curious though, where did you see the logs stored in a different time zone? Could you please send a screenshot of where you encounter these logs in AEST, and the raw data logs as well so I could check?
You can send them privately via email: support@emlid.com. Thank you!
@zac_marshall , I’m not sure which CORS network your using, but Geoscience Australia’s (for example) is definitely in UTC. Are you able to post the Header Information from the logs? (only need about the first 100 lines)
You can also check the time of observation in Emlid Studio. You’ll see the observation time and date at the bottom of the screen after you drop and drag the RINEX file.
