Error: unexpected symbol in "wtc.AB = wtc(t1, t2 nrands)"

I have one issue with WTC (); my data time series is set at 1-hour intervals and in POSCIx format, but my results are always in time stamp epoch format, and the period is always in 6 6-digit number or above. How can I solve this?
I have attached images to show my data and a plot result.
