[R] insertion of a row between individuals

Can someone help with a fairly simple task?
I have a data set where I would like to insert a 0 time event between 
individuals:

what I have:

VAR     DATE    TIME  CONC COVAR
1       NOV2    0.25    10      group1
1       NOV2    0.5     20      group1
1       NOV2    1       5       group1
1       NOV2    2       1       group1
1       NOV2    3       0.1     group1
2       NOV2    0.25    10      group2
2       NOV2    0.5     20      group2
2       NOV2    1       5       group2
2       NOV2    2       0.5     group2
2       NOV2    3       0.01    group2
.
.
1000    NOV2    3       10      group2


...to what I would like to have:
VAR     DATE    TIME  CONC COVAR
1       NOV2    0       0       group1
1       NOV2    0.25    10      group1
1       NOV2    0.5     20      group1
1       NOV2    1       5       group1
1       NOV2    2       1       group1
1       NOV2    3       0.1     group1
2       NOV2    0       0       group2
2       NOV2    0.25    10      group2
2       NOV2    0.5     20      group2
2       NOV2    1       5       group2
2       NOV2    2       0.5     group2
2       NOV2    3       0.01    group2
.
.
1000    NOV2    0       0       group2
1000    NOV2    3       10      group2

Any help would be appreciated.
Thanks,
Kyle

Try this:

newX <- rbind(unique(transform(x, TIME = 0, CONC = 0)), x)
newX[order(newX$VAR),]
