Is there anyway to display system timezone using powershell GET-Timezone -ListAvailble. My requirements is to display this in a dropdownlist in an ASP page. Using .net com is not an option for me now, and even SQL server sys.time_zone_info.

Get-TimeZone

Gets the current time zone or a list of available time zones.

If you run it without parameters it gives the current timezone on the host computer.

Example output:

Id                         : GMT Standard Time
DisplayName                : (UTC+00:00) Dublin, Edinburgh, Lisbon, London
StandardName               : GMT Standard Time
DaylightName               : GMT Daylight Time
BaseUtcOffset              : 00:00:00
SupportsDaylightSavingTime : True

  • How does that help them display it in a Classic ASP page? – user692942 Dec 11 '18 at 09:05
  • thanks for the answer, but I also want to know how to call this from ASP Classic and display this in a dropdownlist, my knowledge in ASP classic is not that good. – Linc Abela Dec 19 '18 at 02:59

You could use Shell.Exec to call the powershell command and read from the standard output.

The powershell part is from Lee_Dailey's answer

<%
Set objShell = server.CreateObject("WScript.Shell")
Set objExec = objShell.Exec("cmd /c powershell [System.TimeZoneInfo]::GetSystemTimeZones().DisplayName")
Set objStdOut = objExec.StdOut


Response.write "<select name=""Timezones"">"

While Not objStdOut.AtEndOfStream
   Response.write "<option>" & objStdOut.ReadLine & "</option>"
Wend

Response.write "</select>"

%>

if all you want is the offset/name for each timezone known to the current system, this will give that list ... 

[System.TimeZoneInfo]::GetSystemTimeZones().DisplayName

as much as some may object, that is powershell. [grin]

    you said you wanted powershell code to get the list. this gets that list with powershell code ... [*grin*] store the list in a $Var and use that to fill the ASP list. – Lee_Dailey Dec 11 '18 at 20:44

    My point is, getting the list in powershell has been covered before. Plus, it’s only part of the answer in which case it’s a duplicate. – user692942 Dec 11 '18 at 21:41

    @Lankymart - ah! i completely misunderstood your question. i thot it was about powershell, not about how to code in ASP. i think you may have made an error in using the powershell tag for this. [*grin*] – Lee_Dailey Dec 11 '18 at 21:56

    @Lankymart - ah! the powershell tag led me to misunderstand your intent. whoever added that may have made an error. – Lee_Dailey Dec 11 '18 at 22:26
  • thanks for the answer, but I also want to know how to use this from ASP Classic and display this in a dropdownlist, im not doing this in a standalone powershell script. – Linc Abela Dec 19 '18 at 02:59
