一个Powershell函数将unix时间转换为字符串？

Question

I'm trying to read the date fields of Firefox places.sqlite datedase using ADO.NET and PowerShell.

Obviously these fields are in Unix time.

I'm looking for a conversion to .Net datetime or string

Edit: I want to bind the datarow to a WPF GridView.

I need either a way to do the conversion within the SQL query or some way while binding the datarows to the grid.

Answer 1

这样的事情会让你走上正确的道路：

[TimeZone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds($unix))

Answer 2

function Convert-UnixTimeToDateTime([int]$UnixTime)
{
    (New-Object DateTime(1970, 1, 1, 0, 0, 0, 0, [DateTimeKind]::Utc)).AddSeconds($UnixTime)
}

This returns an object with the "kind" set to Utc. Then, if you want local time, call the ToLocalTime method on the resulting object.

Answer 3

[timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds(1303743289))

Answer 4

The working solution to my problem is

SELECT datetime (b.dateAdded / 1000000, 'unixepoch', 'localtime') dateAdded  from moz_bookmarks

BTW it is partly hidden in the the original documentation .

The other part is that you have to find out, that you must divide the integer by 1000000 to get the seconds.
