Dear R-experts,

Need your help.

Dear R- Experts, 

Seek your help. 

I created a time sequence using: 
x[i] <-chron(dates, tt, format=c(dates="y-m-d", tt="h:m:s")) 
first element in the list is displayed as: (09-01-01 00:00:00) 
Further elements are:
(09-01-01 00:01:00)
(09-01-01 00:02:00)
(09-01-01 00:03:00)
and so on.

I want to compare each value with the timestamp values from database.
I cannot simply compare above values with the timestamp values, as the above
values are not in "date" format.

Therefore, I used: 
format.Date(x[1],"%y-%m-%d %H:%M:%S"), I expect following value: 
"09-01-01 00:00:00" 

HOWEVER, the value displayed as: "09-01-01 01:00:00" 

Unnecessary addition of 1 hour.
I want to create time sequence starting from "09-01-01 00:00:00" !!! 
Can any one please help?

Thank you.
