st: Problem declaring a panel dataset

[Milena Przheska <milena.przheska@cosmicdevelopment.com>]

Dear Statalist members,

I am getting the following error when declaring a panel dataset:

"repeated time values within panel"

I have checked for duplicate records using the following command:

bys code when: gen dup = cond(_N==1,0,_n)

I get this description of duplicates with -tab-

       dup |      Freq.     Percent        Cum.
------------+-----------------------------------
          0 |    164,787       91.61       91.61
          1 |      7,241        4.03       95.63
          2 |      7,241        4.03       99.66
          3 |        499        0.28       99.93
          4 |         71        0.04       99.97
          5 |         18        0.01       99.98
          6 |         14        0.01       99.99
          7 |          8        0.00      100.00
          8 |          8        0.00      100.00
------------+-----------------------------------
      Total |    179,887      100.00


But when I listed duplicates, this is what I could see:


list if dup>1

 when                                code     dup
28apr2013 08:20:55               a          2
28apr2013 08:21:06               a          2
04may2013 10:44:43             a          2
04may2013 10:45:28             a          2


The variable "when' is in %tc format, and I use the same format when
declaring a panel dataset. Yet, Stata seems to only look at the date,
not the hour, minute and seconds part of the variable.

Can anyone please tell me what can I do to correct this situation?

I appreciate your help and I thank you in advance.


Best,
Milena Przheska
