TSV String, Filter by Datetime

// GraalJS Script (engine type: 2)
// (c) 2021, Questetra, Inc. (the MIT License)
// Notes:
// Supported datetime format is "YYYY-MM-DD HH:MM".
// For "AND search", try to place this Automated Step serially.
// Equals at range boundary values are included in the filter range.
//  (No Problem "2021-10-05 00:00<2021-10-05 00:00")
//
// Notes(ja):
// 対応する日時フォーマットは "YYYY-MM-DD HH:MM" です
// "AND検索" は自動工程の直列配置をお試しください
// 範囲境界値におけるイコールはフィルタ範囲に含まれます
// （問題のないフィルタ例 "2021-10-05 00:00<2021-10-05 00:00"）
