Timestamp

[Yoseph-Arba]

When I try to add a new column for Timestamp it works but with warning, so is there any one comment on my code?
The date is written as follows:
1/1/2001
1/2/2001
1/3/2001
.....
My code is.....
josData['Timestamp'] = pd.to_datetime(josData.Datetime, dayfirst=True)
josData

it works but with warning

What does the warning say?
The warning might be related to your date organization. You show part of your date format. Is your format in Month/Day/Year or Day/Month/Year? If it is Month/Day/Year, you should use josData['Timestamp'] = pd.to_datetime(josData.Datetime) instead of josData['Timestamp'] = pd.to_datetime(josData.Datetime, dayfirst=True). Including dayfirst=True is to let Pandas know that your format is Day/Month/Year. Excluding dayfirst=True means that Pandas will assume a Month/Day/Year format.
