The minimum unit of Unix timestamp is second, And the start time is Greenwich Mean Time 00:00:00
The basic idea of the ConvertIntDateTime method is to get the local time zone to indicate the Unixk start time, plus the Unix time value (that is, the past number of seconds ).
The basic idea of the ConvertDateTimeInt method is to convert the number of scales to the number of seconds by the difference in the number of scales. Of course, it must be noted that I return the double type here, in a sense, it is not a real Unix timestamp format.
To obtain the real Unix timestamp, you only need to obtain the integer part.
