Convert Date time into Flexsim seconds number

Is there a simple way to convert a string like: "2014-11-13 13:55:42" into the seconds number used as Start Time written into "MODEL:/Tools/ModelUnits/ModelDateTime/start"?

I know that it can be converted using the query but I used Flexcript solution.
If needed i write it here:

string Data = "2014-01-01 00:00:00";

int year = stringtonum(stringpart(Data,0,4));
int month = stringtonum(stringpart(Data,5,2));
int day = stringtonum(stringpart(Data,8,2));
int hours = stringtonum(stringpart(Data,11,2));
int minutes = stringtonum(stringpart(Data,14,2));
int seconds = stringtonum(stringpart(Data,17,2));
treenode starttimenode = tonode(getmodelunitnum(START_TIME_NODE));
int anni = year - 1601;
int b_years = 0;
int ii;
for (ii = 1602; ii < year; ii++)
{
if (ii % 400 == 0 || (ii % 100 != 0 && ii % 4 == 0))
b_years ++;
}
int days = b_years * 366 + (anni - b_years) * 365;
switch (month)
{
case 2: days += 31; break;
case 3: days += 59; break;
case 4: days += 90; break;
case 5: days += 120; break;
case 6: days += 151; break;
case 7: days += 181; break;
case 8: days += 212; break;
case 9: days += 243; break;
case 10: days += 273; break;
case 11: days += 304; break;
case 12: days += 334; break;
}
if (month > 2 && (year % 400 == 0 || (year % 100 != 0 && year % 4 == 0)))
days ++;
days += (day - 1);
double total = days * 86400 + hours * 3600 + minutes * 60 + seconds;
return total;
