-lt is a numeric operator. What format are these dates in? The best format for numerical comparison of dates is always YYYYMMDDHHMMSS. Can you change the dates to this format?

Tcl_ExprLongObj(3) Tcl Library Procedures Tcl_ExprLongObj(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tcl_ExprLongObj, Tcl_ExprDoubleObj, Tcl_ExprBooleanObj, Tcl_ExprObj - evaluate an expression
SYNOPSIS
#include <tcl.h>
int
Tcl_ExprLongObj(interp, objPtr, longPtr)
int
Tcl_ExprDoubleObj(interp, objPtr, doublePtr)
int
Tcl_ExprBooleanObj(interp, objPtr, booleanPtr)
int
Tcl_ExprObj(interp, objPtr, resultPtrPtr)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter in whose context to evaluate objPtr.
Tcl_Obj *objPtr (in) Pointer to an object containing the expression to evaluate.
long *longPtr (out) Pointer to location in which to store the integer value of the expression.
int *doublePtr (out) Pointer to location in which to store the floating-point value of the expression.
int *booleanPtr (out) Pointer to location in which to store the 0/1 boolean value of the expression.
Tcl_Obj **resultPtrPtr (out) Pointer to location in which to store a pointer to the object that is the result of the expression.
_________________________________________________________________
DESCRIPTION
These four procedures all evaluate an expression, returning the result in one of four different forms. The expression is given by the
objPtr argument, and it can have any of the forms accepted by the expr command.
The interp argument refers to an interpreter used to evaluate the expression (e.g. for variables and nested Tcl commands) and to return
error information.
For all of these procedures the return value is a standard Tcl result: TCL_OK means the expression was successfully evaluated, and
TCL_ERROR means that an error occurred while evaluating the expression. If TCL_ERROR is returned, then a message describing the error can
be retrieved using Tcl_GetObjResult. If an error occurs while executing a Tcl command embedded in the expression then that error will be
returned.
If the expression is successfully evaluated, then its value is returned in one of four forms, depending on which procedure is invoked.
Tcl_ExprLongObj stores an integer value at *longPtr. If the expression's actual value is a floating-point number, then it is truncated to
an integer. If the expression's actual value is a non-numeric string then an error is returned.
Tcl_ExprDoubleObj stores a floating-point value at *doublePtr. If the expression's actual value is an integer, it is converted to float-
ing-point. If the expression's actual value is a non-numeric string then an error is returned.
Tcl_ExprBooleanObj stores a 0/1 integer value at *booleanPtr. If the expression's actual value is an integer or floating-point number,
then they store 0 at *booleanPtr if the value was zero and 1 otherwise. If the expression's actual value is a non-numeric string then it
must be one of the values accepted by Tcl_GetBoolean such as "yes" or "no", or else an error occurs.
If Tcl_ExprObj successfully evaluates the expression, it stores a pointer to the Tcl object containing the expression's value at *resultP-
trPtr. In this case, the caller is responsible for calling Tcl_DecrRefCount to decrement the object's reference count when it is finished
with the object.
