void enforceValid(string units)(int  value,  string file =  __FILE__,  size_t line =  __LINE__) if (units ==  "months" ||

     units ==  "seconds")

@safe pure

Parameters

`units`	The units of time to validate.
`value`	The number to validate.
`file`	The file that the DateTimeException will list if thrown.
`line`	The line number that the DateTimeException will list if thrown.

Throws

DateTimeException if valid!units(value) is false.

void enforceValid(string units)(int  year,  Month month,  int  day,  string file =  __FILE__,  size_t line =  __LINE__) if (units ==  "days")

@safe pure

Because the validity of the day number depends on both on the year and month of which the day is occurring, take all three variables to validate the day.

Parameters

`units`	The units of time to validate.
`year`	The year of the day to validate.
`month`	The month of the day to validate.
`day`	The day to validate.
`file`	The file that the DateTimeException will list if thrown.
`line`	The line number that the DateTimeException will list if thrown.

Throws

DateTimeException if valid!"days"(year, month, day) is false.
