Since you don't specify any particular regex type or where it might occur in input; this is an example [0-9][0-9]:[0-9][0-9].
由于您未指定任何特定的正则表达式类型或输入中可能出现的位置;这是一个例子[0-9] [0-9]：[0-9] [0-9]。
If you want to match the whole input to just being exactly on that format ^[0-9][0-9]:[0-9][0-9]$ .. etc.
如果你想匹配整个输入只是正好在那个格式^ [0-9] [0-9]：[0-9] [0-9] $ ..等
