System::Call '*(&i2,&i2,&i2,&i2,&i2,&i2,&i2,&i2)i.s'
System::Call /NOUNLOAD 'kernel32::GetLocalTime(isr0)'
System::Call '*$0(&i2.r1,&i2.r2,&i2,&i2.r3,&i2.r4,&i2.r5,&i2,&i2)'
System::Free $0
IntFmt $1 "%0.4d" $1
IntFmt $2 "%0.2d" $2
IntFmt $3 "%0.2d" $3
IntFmt $4 "%0.2d" $4
IntFmt $5 "%0.2d" $5
DetailPrint "datetime=$1$2$3$4$5"
