Due to William Jackson's answer, I found a similar question on Stack Overflow.
The accepted answer states to use Powershell and these commands:
$(Get-Item ).creationtime=$(Get-Date "mm/dd/yyyy hh:mm am/pm")
$(Get-Item ).lastaccesstime=$(Get-Date "mm/dd/yyyy hh:mm am/pm")
$(Get-Item ).lastwritetime=$(Get-Date "mm/dd/yyyy hh:mm am/pm")
Edit
Two examples:
(This one is from the comments:) Set the last-access time for a file aaa.csv to the current time:
$(Get-Item aaa.csv).lastwritetime=$(Get-Date)
Set the creation time of a file foo.txt to November 24, 2015, at 6:00am:
$(Get-Item foo.txt).creationtime=$(Get-Date "11/24/2015 06:00 am")

13A slight variation that is recursive and a little shorter, though less readable: "gci -rec | %{ $_.lastWriteTime = ($_.lastAccessTime = ($_.creationTime = (get-date "2011-09-14T07:10:00"))) }" Sep 14, 2011 at 6:36

11For people that don't know much about Powershell, you have to put the filename after Get-Item. You can also omit the string after Get-Date to set the attribute to the current date/time like the default behavior of the touch command. Finally you can pass that code as an argument to the powershell command to have it just execute that from an existing batch file. Example:
powershell $(Get-Item aaa.csv).lastwritetime=$(Get-Date)– sjbothaSep 4, 2013 at 14:03 -

5The date and time format is not as per the command, but the system wide one (so, in my system, it was dd/mm/yyy). Dec 5, 2017 at 1:31

3For every file in directory :
Get-ChildItem -File | foreach { $_.CreationTime=$(Get-Date) }Dec 27, 2020 at 18:24
See the answers to this question.
Specifically, this can be done natively with:
copy /b filename.ext +,,
This will set the timestamp to the current time.
Documentation for the copy command is on TechNet.
The commas indicate the omission of the Destination parameter.

4Can you explain how that is working? What is the
+,,? How do I know what date it is being set to? Jun 3, 2011 at 20:05 -
1@josmh Check the documentation link for details. The timestamp gets set to the current time when you run the command. Are you implying that you want to be able to change the timestamp to an arbritary time of your choosing? Jun 3, 2011 at 20:10

1Main problem with this is when the file is not in current directory... it will copy the file to current directory instead of "touching" it in place. Aug 9, 2017 at 19:12

2@KaseySpeakman - this command relies on being in the current directory. Use
pushd FILEDIR, before the comand andpopdafter– TydaeusJun 25, 2018 at 18:32
Nirsoft to the rescue: try the freeware tool nircmd. It's a bunch of useful tools in one small command line program. One of the commands allows you to specify either or both of created time and modified time, like this:
nircmd.exe setfiletime "c:\temp\myfile.txt" "24-06-2003 17:57:11" "22-11-2005 10:21:56"

5Also if you want to transfer time from a file to another, clonefiletime filefrom fileto works best!– JasonXAJun 26, 2015 at 19:42

3This worked perfectly for me
touch -t 201608221400 filenameto set it to 22.08.2016 14:00:00. Nov 24, 2016 at 9:55
Check out the following webpage: http://www.stevemiller.net/apps/
The Win32 Console Toolbox contains a utility called 'touch' that lets you modify the times on one or more files. I believe it only works with US format times, though.
touchthat sets a files's timestamp to the current time.touch, I could specify the date. en.wikipedia.org/wiki/Touch_(Unix). Something is wrong with the auto linking though, make sure you get both parentheses.man touch. You have taught me something new.
