Convert to timeseries hourly data

I have a data frame with dates going from 2012-04-18 00:00:00 to 2012-04-30 23:00:00.

I want to convert it to a time series using the ts function but I can't manage to configure it.

I have tried: 

newdata <- ts(data[-1], start = as.Date("2012-04-18"), freq = 312)

but it doesn't seem to work.

the syntax for the ts function is a little different. As it is written on the help page of ts:

start: the time of the first observation. Either a single number or a vector of two integers, which specify a natural time unit and a (1-based) number of samples into the time unit. See the examples for the use of the second form.

Try this:

newdata <- ts(data[-1], start = c(2012, 4.5), freq = 312).

However when working with intraday data I would rather recommend the xts package and work with xts objects instead on ts objects.
