  Sample output:

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

/*=================================================

FORM: IsTime ( _var )

PURPOSE: return valid time as number of seconds or nothing if invalid

PARAMETER: _var format: unknown value: variable

RESULT: number of seconds or NOTHING if invalid

DEPENDENCY: -

NOTE: for boolean result check with IsEmpty ( IsTime ( _var )) instead of GetAsBoolean ( IsTime ( _var )) since IsTime ("0:0") is valid
see my other function IsTimeOfDay( _var )

EXAMPLE: IsTime ( "1:0:1" ) => 3601
IsTime ( "122330" ) => ""
IsTime ( "1:71:71" ) => 7931 (valid FMP-time!)
