Ideally, the output structure should emit a type field to show if pattern is really a date or not. Something like this:

typeFormatDateInfo={// new date type fieldtype: "date"|"time"|"datetime"|"none",clockType: 12|24,seconds: boolean,minutes: boolean,hours: boolean,day: boolean,month: boolean,year: boolean,}

This has the benefit that:

  1. You don't have to call isDateFormat to determine if something is a date beforehand.
  2. You can pass the info.time into a map of default patterns:
constISO_PATTERNS={date: "yyyy-mm-dd",time: "hh:mm:ss",datetime: "yyyy-mm-ddThh:mm:ss",none: "General",};// return an ISO formatted date, or a general formatted number, based on a cell format pattern:constinfo=getFormatDateInfo(pattern);constnormalizedPattern=ISO_PATTERNS[info.type];returnformat(normalizedPattern,value);

Alternatively, we might consider a isDate + granularity approach:

typeFormatDateInfo={// new "is a date or not" fielddate: boolean,// new granularity fieldgranularity: "year"|"month"|"day"|"hours"|"minutes"|"seconds"|"none",
...
}

This does make it impossible to differentiate the "time" type though, so maybe it makes sense to do both.

                          Ideally, the output structure should emit a type field to show if pattern is really a date or not. Something like this:
                          typeFormatDateInfo={// new date type fieldtype: "date"|"time"|"datetime"|"none",clockType: 12|24,seconds: boolean,minutes: boolean,hours: boolean,day: boolean,month: boolean,year: boolean,}
                          This has the benefit that:
                          1. You don't have to call isDateFormat to determine if something is a date beforehand.
                          2. You can pass the info.time into a map of default patterns:
                          constISO_PATTERNS={date: "yyyy-mm-dd",time: "hh:mm:ss",datetime: "yyyy-mm-ddThh:mm:ss",none: "General",};// return an ISO formatted date, or a general formatted number, based on a cell format pattern:constinfo=getFormatDateInfo(pattern);constnormalizedPattern=ISO_PATTERNS[info.type];returnformat(normalizedPattern,value);
                          Alternatively, we might consider a isDate + granularity approach:
                          typeFormatDateInfo={// new "is a date or not" fielddate: boolean,// new granularity fieldgranularity: "year"|"month"|"day"|"hours"|"minutes"|"seconds"|"none",
...
}
                          This does make it impossible to differentiate the "time" type though, so maybe it makes sense to do both.
