フォーマットされた時間 (HH:MM:SS) を秒に変換します。
このツールを使うと、フォーマットされた時刻文字列（HH:MM:SS）を秒数に変換できます。期間や時間間隔を計算するのに便利です。
In this example, we convert multiple clock times to seconds. Each clock time is listed on a new line and the spacing between input times is preserved in the output.
00:00:00 00:00:01 00:01:00 01:00:00 01:59:59 12:00:00 18:30:30 23:59:59 24:00:00
0 1 60 3600 7199 43200 66630 86399 86400
This example finds how many seconds there are in clock times that are partially written. Some of the clock times contain just the hours and some others contain just hours and minutes.
1 1:10 14:44 23
3600 4200 53040 82800
In this example, we go beyond the regular 24-hour clock. In fact, we even go beyond 60 minutes and 60 seconds.
24:00:01 48:00:00 72 00:100:00 100:100:100
86401 172800 259200 6000 366100
