StringToDays (String function)

Convert string date/time to days since 1900 (String class)

[Introduced in Sirius Mods 7.8]

StringToDays is an intrinsic function to convert a date/time string to days since 1900.

Syntax

%days = string:StringToDays( format, [[CentSpan=] number]) Throws InvalidDateString

Syntax terms

%days	The float variable to receive the computed time since 1900.
string	The input date/time string, which must be in the format specified by format.
format	The format of the date/time string. See "Datetime formats".
CentSpan	The CENTSPAN value used, if the format has a two-digit year. The default is specified by the CENTSPAN parameter. In Sirius Mods 7.9 and later this is a name allowed parameter. For versions prior to 7.9, it is a positional parameter.

Usage notes

• If the format is invalid, the request is cancelled.
• If the date contents of the method object string is invalid, an InvalidDateString exception is thrown.
• If the CentSpan value is invalid, the request is canceled.
• Values returned by StringToDays can be stored in a BINARY or FLOAT4 field, if you want.
• Dates prior to 1 January 1900 return a negative number.
• The inverse of this function is DaysToString.
