st: Type of data (time-series and panel-data)

Dear statalisters,

I have a question concerning the type of data in my dataset.

I have data about five different bonds, with observations for the
time, the date and other variables, such as the bid and ask prices.

I would like to treat my data both as a time-series (i.e. paying no
attention to the type of bond) and as a panel-data.
However, when I use the command tsset I receive this message:
repeated time values in sample

I think that this is due to the fact that I have the same date for
different times and for different variables,because, for example, I
have at the same date a bid price for a given time, an ask price for
the same data and time and so on.

Does anyone know how to solve the problem both for time-series and panel-date?

Thank you very much.

Best regards,
