StrToDateTime

String manipulation 
SYNTAX  StrToDateTime( ''string'' ) 
RETURNS  NUMBER 
FUNCTION  Converts string representing date/time value to the corresponding DateTime number (that can be later compared to output of DateTime() function for example). This function has shorter synonym: _DT function. VERSION 5.27 and above: It is important to understand that DateTime is not a simple number but rather bitset and two datetime values can only be reliably compared for equlity or inequality using == or != operators. Any other comparisions (less than/greater then) using normal operators > < can lead to wrong results, therefore to compare two datetime numbers you should use DateTimeDiff( arg1, arg2 ) which will return positive values if arg1 > arg2 and negative values if arg1 < arg2. 
EXAMPLE  Buy = DateTime()
== StrToDateTime("2005Mar05");
