Indeed it works. Thank you very much.

On the other, the documentation says that the format should be yyyy:mm for monthly date values on page 21 in User Guide.

For dates to be recognized as such, the date strings must adhere to one or other of a set of
specific formats, as follows. For annual data: 4-digit years. For quarterly data: a 4-digit year,
followed by a separator (either a period, a colon, or the letter Q), followed by a 1-digit quarter.
Examples: 1997.1, 2002:3, 1947Q1. For monthly data: a 4-digit year, followed by a period or
a colon, followed by a two-digit month. Examples: 1997.01, 2002:10.

Maybe the documentation needs to be updated. 

Best regards,

Hi,

Can't read date column into gretl. I've read the manual, formatted the column as gretl would expect (file is attached). But when I want to read the file I receive and error message saying "can't make sense of the extra bit". 
It seems, gretl sees the internal excel date value which is a number representing the date value as the number of days since 1/1/1900 (A serial number 1 represents 1/1/1900 internally in Excel). 
Tried many variations with no luck.

Assuming this might be due to local regional settings (which were Turkish) having different date formats, I switched to English (USA) settings and tried, but did not work. 

Any ideas ? 

Thanks,
Bulent Erdemir
