Dear list,

This question is probably off the topic, but in order to test my data with
GLMM, I need to transform the DateTime of my GPS data from:

"666.1751" into yyyy/mm/dd hh:mm:ss

I have the following code:

d$Date <- ISOdatetime(2009, 1, 1, 0, 0, 0, tz = "GMT")+d$Date*(24*3600)

This gives me: 2010-10-29 04:12:09, which is wrong. It should be 2010-10-29
06:12:09

Another example:

418.3219 corresponds to: 2010-02-23 07:43:30, but it should be 2010-02-23
08:43:30.

Any ideas or suggestions, where I could find the answer, are very much
appreciated.

Best regards,

Julia

PS. I've tried to find the answer in all sorts of R help forums and also in
my R books - no luck so far. Maybe I'm missunderstanding the entire
ISOdatetime function?
