COXPH TIME-DEPENDENT

Dear R-community, 

which of the following two formats is correct? Are both correct? 

Please, consider this example: 

data table: 

Data
   S sta time  TDC1 total_time
A 1   0   1  48.50       1
B 0   0   1  65.96       2
B 1   1   2  65.08       2
C 0   0   1  0.00        2
C 1   1   2  0.00        2
D 0   0   1 72.74        2
D 1   1   2 72.52        2
E 0   0   1 61.84         2
E 0   1   2 60.56        2
F 0   0   1 35.04        4
F 0   1   2 36.97        4
F 0   2   3 37.92        4
F 1   3   4 39.01        4

time - time to event
sta - starting time
TDC - time dependent covariates
total_time - total time at risk

option A

coxph(Surv(time,S) ~ time_dependent_covariates,
data=data.frame(Data))
 
option B

coxph(Surv(sta,time,S) ~ time_dependent_covariates,
data=data.frame(Data))

option C

coxph(Surv(total_time,S) ~ time_dependent_covariates,
data=data.frame(Data))


How can time at risk be visualized in the coxph output?

Best regards, 

Javier
