Hey dears,

I have a problem with time series and with a method called getsampleusingtime. I have a ts object and the times are in format eg. 13-Jun-2010 17:00:00.

Im trying to extract certain periods of this data to new ts objects with getsampleusingtime like this:
ts = getsampleusingtime(DATA, datenum(2010, 6, 13, 17, 0, 0), datenum(2010, 6, 13, 17, 4, 59));

But Im getting error like this:
??? Error using ==> timeseries.getsampleusingtime at 82
The specified time value is duplicated in the timeseries. Set the AllowDuplicateTimes flag when calling GETSAMPLEUSINGTIME to obtain samples at a duplicate time

It says I would need to set some flag but I can´t figure out what flag I should set and how. There´s no property AllowDuplicateTimes for ts objects and google doesn´t even recognize that phrase.

I think this is weird, can you help me?

Best, Themis

The help states the syntax is:

ts2 = getsampleusingtime(Data,Time,'ALLOWDUPLICATETIMES',true);
