Internal Date/Time functions

These functions use a Float to represent a date time, similar to TDateTime (1 unit per day, same time origin as in Delphi).

• [InternalNow Now]() : returns the current date time
• [InternalDate Date]() : returns the current date
• [InternalTime Time]() : returns the current time

• [InternalUTCDateTime UTCDateTime]() : returns the current UTC date time

• [InternalDateTimeToStr DateTimeToStr](dt : Float) : converts a date time to a string representation
• [InternalStrToDateTime StrToDateTime](str : String) : parses a string representing a date time
• [InternalStrToDateTimeDef StrToDateTimeDef](str : String; def : Float) : parses a string representing a date time, returns def if the string isn't a valid date time

• [InternalDateToStr DateToStr](dt : Float)
• [InternalStrToDate StrToDate](str : String)
• [InternalStrToDateDef StrToDateDef](str : String; def : Float)

• [InternalDateToISO8601 DateToISO8601](dt : Float) : converts a date to its ISO8601 string representation
• [InternalDateTimeToISO8601 DateTimeToISO8601](dt : Float) : converts a date time to its ISO8601 string representation

• [InternalTimeToStr TimeToStr](dt : Float)
• [InternalStrToTime StrToTime](str : String)
• [InternalStrToTimeDef StrToTimeDef](str : String; def : Float)

• [InternalDayOfWeek DayOfWeek](dt : Float) : returns the day of the week between 1 and 7 with Sunday as the first day
• [InternalDayOfTheWeek DayOfTheWeek](dt : Float) : returns the day of the week between 1 and 7 with Monday as the first day
• [InternalFormatDateTime FormatDateTime](frm: String; dt: Float)
• [InternalIsLeapYear IsLeapYear](year : Integer) : indicates if a year is a leap year
• [InternalIncMonth IncMonth](dt : Float; nb : Integer) : returns a date time offset by nb months (nb can be negative or positive)
• [InternalDecodeDate DecodeDate](dt : Float; var y, m, d : Integer)
• [InternalEncodeDate EncodeDate](y, m, d) : Integer
• [InternalDecodeTime DecodeTime](dt : Float; var h, m, s, ms : Integer)
• [InternalEncodeTime EncodeTime](h, m, s, ms : Integer)
