This is how internal clocking in the receiver works, so there is no option to change it. This is completely in line with RINEX spec, so should be processed by software just fine.
I can confirm that after post processing in rtklib in kinematic mode, the resulting time stamps are rounded off to nearest 1 second intervals if this was set in both your base & rover recording intervals.
My target software is NGS OPUS. I have tried collecting .UBX files and converting them, and RINEX files directly with 1-second rates. In both cases the submitted files are rejected by OPUS with this message:
1009 WARNING! No antenna type was selected. No antenna offsets or
1009 pattern will be applied. Coordinates with reduced accuracy
1009 will be returned for the antenna phase center.

1020 OPUS aborted on the submitted data file for one or more of the following
1020 reasons. OPUS cannot process the data file.
1020 1. Collection interval of the data file was not one of the allowed rates.
1020 The intervals that are accepted are 1,2,3,5,10,15,30 seconds.
**> 1020 2. The time of each epoch is offset from one of the above intervals. The ** > 1020 seconds epoch field must coincide with one of the above rates.
1020 3. The data file may have been collected in kinematic mode. OPUS does not
1020 process kinematic data files.
1020 4. Note: OPUS processes data every 30 seconds, and 2+ hour files
1020 collected at the 1 second rate should be changed to 30 seconds.
1020 5. If your data were collected today or yesterday, we may not have
1020 sufficient CORS data - try resubmitting your file tomorrow.

I think that item 2 “…epoch is offset…” is probably the offending issue (I have waited several days for submission.) Is there a document that describes a “known to work with OPUS” workflow?
So I tried to upload an RS2 rinex file to OPUS and indeed it says it does not accept uneven time intervals. Here’s the error message:

Tried the settings that you suggested and still getting time decimal part. I think Emlid should address this issue as using OPUS is a vital part of post processing. I would like to say that post processing in Magnet or RTKLib has no problems with the decimal time. Only in OPUS.
So when does the decimal part appear in the rinex file? check or uncheck? I have tried every combination in the options page & I am still getting a time decimal part,
To check or uncheck, this is the question
Time decimal part it only appeared once when starting the program. The program version is probably important. I have it

I read that NRCAN PPP does not use existing GPS stations/CORS. It’s a PPP process which has meter level accuracry. Maybe I am wrong so correct me if I misunderstood its process.
Please note: The 2.4.3 bXX is the development or beta version with experimental implementations.
