我正在尝试使用时区在我的系统上显示本地时间。如何在任何系统上以最简单的方式以这种格式显示时间？
时间：美国东部时间上午 8：00：34
我目前正在使用以下脚本：
$localtz = [System.TimeZoneInfo]::Local | Select-Object -expandproperty Id
if ($localtz -match "Eastern") {$x = " EST"}
if ($localtz -match "Pacific") {$x = " PST"}
if ($localtz -match "Central") {$x = " CST"}
"Time: " + (Get-Date).Hour + ":" + (Get-Date).Minute + ":" + (Get-Date).Second + $x
我希望能够在不依赖简单逻辑的情况下显示时间，但能够在任何系统上给出本地时区。
虽然
这有点...也许很天真，这是在没有 switch 语句的情况下获取缩写的一种方法：
[Regex]::Replace([System.TimeZoneInfo]::Local.StandardName, '([A-Z])w+s*', '$1')
我的正则表达式可能还有一些不足之处。
对于我的时区，上述输出是 EST .我做了一些查看，因为我想看看其他 GMT 偏移量设置的值是多少，但 .NET 似乎在DateTime和TimeZoneInfo之间没有很好的链接，所以我不能只是以编程方式运行它们来检查。对于某些返回StandardName的字符串，这可能无法正常工作。
编辑：我做了更多的调查，手动更改计算机上的时区以检查这一点，GMT+12的TimeZoneInfo如下所示：
PS> [TimeZoneInfo]::Local
Id : UTC+12
DisplayName : (GMT+12:00) Coordinated Universal Time+12
StandardName : UTC+12
DaylightName : UTC+12
BaseUtcOffset : 12:00:00
SupportsDaylightSavingTime : False
这为我的代码生成了以下结果：
PS> [Regex]::Replace([System.TimeZoneInfo]::Local.StandardName, '([A-Z])w+s*', '$1')
U+12
所以，我想你必须检测StandardName似乎是一组单词还是只是偏移名称，因为它没有标准名称。
美国以外的问题较少的人似乎遵循三个单词的格式：
PS> [TimeZoneInfo]::Local
Id : Tokyo Standard Time
DisplayName : (GMT+09:00) Osaka, Sapporo, Tokyo
StandardName : Tokyo Standard Time
DaylightName : Tokyo Daylight Time
BaseUtcOffset : 09:00:00
SupportsDaylightSavingTime : False
PS> [Regex]::Replace([System.TimeZoneInfo]::Local.StandardName, '([A-Z])w+s*', '$1')
TST
您应该研究DateTime格式字符串。虽然我不确定他们是否可以返回时区短名称，但您可以轻松地获得 UTC 的偏移量。
$formatteddate = "{0:h:mm:ss tt zzz}" -f (get-date)
这将返回：
8:00:34 AM -04:00
不愿意定义另一种日期时间格式！使用现有的，例如 RFC 1123。甚至还有一个PowerShell快捷方式！
Get-Date -format r
周四， 14 六月 2012 16：44：18 GMT
参考： 获取日期
这是一个更好的答案：
$A = Get-Date #Returns local date/time
$B = $A.ToUniversalTime() #Convert it to UTC
# Figure out your current offset from UTC
$Offset = [TimeZoneInfo]::Local | Select BaseUtcOffset
#Add the Offset
$C = $B + $Offset.BaseUtcOffset
$C.ToString()
输出：2017/3/20 23：55：55
我不知道
有任何对象可以为您完成工作。您可以将逻辑包装在一个函数中：
function Get-MyDate{
$tz = switch -regex ([System.TimeZoneInfo]::Local.Id){
Eastern {'EST'; break}
Pacific {'PST'; break}
Central {'CST'; break}
}
"Time: {0:T} $tz" -f (Get-Date)
}
Get-MyDate
或者甚至取时区 id 的首字母：
$tz = -join ([System.TimeZoneInfo]::Local.Id.Split() | Foreach-Object {$_[0]})
"Time: {0:T} $tz" -f (Get-Date)
我只是组合了几个脚本，终于能够在域控制器中运行该脚本。
该脚本为域下连接的所有计算机提供时间和时区的输出。我们的应用程序服务器遇到了一个主要问题，并使用此脚本交叉检查时间和时区。
# The below scripts provides the time and time zone for the connected machines in a domain
# Appends the output to a text file with the time stamp
# Checks if the host is reachable or not via a ping command

如果您有互联网连接...应用程序接口

减去脚本看到的内容
有时，TimeZoneInfo Local 与脚本查找的内容不同。例如，我注意到我的偏离了一个小时，其中报告了 -5，但 PS 脚本（获取日期）是 -4。在可能的情况下，也使用 [datetime]：：UtcNow 而不是 get-date。
解释：
而不是依赖本地时间"[时区信息]：：本地 |选择BaseUtcOffset'，找出两个日期之间的脚本差异
((Get-Date).ToUniversalTime() - (Get-Date)).TotalHours
- 注意：这假设 UTC 以西，否则反转数学或更改为 +。
这是一组有趣的答案，因为很大程度上取决于您希望如何查看时区的缩写形式。 有些带有数字偏移量，有些只是文本。 这是我对字母数字时区缩写的解决方案，处理夏令时，以及处理没有"标准名称"的情况。 我已经测试了美国版 Windows 10 中可用的时区，虽然它们并不都是唯一或准确的，但它可以满足我的需求。 我将不胜感激任何反馈：
function Get-TimeZoneAbbreviation {
[CmdletBinding()] param ([TimeZoneInfo]$timeZoneInfo = [TimeZoneInfo]::Local, $daylightSavingsTime = $null)
$result = ""
# If DST parameter is left empty, calculate DST from current time in that time zone.
if ($daylightSavingsTime -eq $null) {
$daylightSavingsTime = $timeZoneInfo.IsDaylightSavingTime([TimeZoneInfo]::ConvertTimeFromUtc([DateTime]::UtcNow, $timeZoneInfo))
}
# If DST is supplied as true, but isn't supported return null.
elseif ($daylightSavingsTime -and !$timeZoneInfo.SupportsDaylightSavingTime) {
return $null
}
# Get standard or daylight name.
$tzFullName = $timeZoneInfo.StandardName
if ($daylightSavingsTime) {
$tzFullName = $timeZoneInfo.DaylightName
}
# If name doesn't have multiple words then just return the name.
$tzSplit = $tzFullName.Split(" ")
if ($tzSplit.Length -eq 1) {
return $tzFullName
}
# Return abbreviation as first character of each word.
foreach ($tzC in $tzSplit) {
$result += [regex]::Replace($tzC, "[^a-zA-Z0-9 -]", "").Substring(0, 1)
}
return $result
}
用法（我只指定字符串，所以我可以使用 PadRight 进行输出）：
# Output for original question:
[string]$tzaLocalNow = @(Get-TimeZoneAbbreviation)
"Local Time Now: " + @(Get-Date -Format "HH:mm:ss ") + $tzaLocalNow
# Output using DST parameter
[string]$tzaLocalStandard = @(Get-TimeZoneAbbreviation -daylightSavingsTime $false)
[string]$tzaLocalDaylight = @(Get-TimeZoneAbbreviation -daylightSavingsTime $true)
Write-Host @("`n" + $tzaLocalNow.PadRight(10) + $tzaLocalStandard.PadRight(10) + $tzaLocalDaylight + "`n")
# Output table of all system time zone abbreviations.
foreach ($tz in (Get-TimeZone -ListAvailable)) {
[string]$tzaNow = @(Get-TimeZoneAbbreviation $tz)
[string]$tzaStandard = @(Get-TimeZoneAbbreviation $tz $false)
[string]$tzaDaylight = @(Get-TimeZoneAbbreviation $tz $true)
Write-Host @($tzaNow.PadRight(10) + $tzaStandard.PadRight(10) + $tzaDaylight)
}
