# Replace test in array

so i have an array of users around 17,000.

there are lots of columns but for this i will stick with 2

```\$users

Name               Lastlogontimestamp
User1              131648355872511827
User2              131652816687365046
User3              131653273083137594

```

i want to replace the \$users.laslogontimestamp with the \$userts entry
what i have so far is producing the date but im struggling to get it back into the original \$users

```

foreach (\$user in \$users)
{
\$userts = [DateTime]::FromFileTime(\$user.lastlogontimestamp)
\$userts -replace \$user.lastLogonTimestamp
}

```

Wouldn’t be something like this enough?

`\$user.lastlogontimestamp = [DateTime]::FromFileTime(\$user.lastlogontimestamp)`

Many thanks Olaf, again think i was trying to overthink it
