Time-based while loop - powershell

Question

I've been trying to get the while & the If loop to read in the time correctly, but it doesn't end the program when the right time has hit. I tried using single quotes '' and double quotes "", as well as different syntax like (-eq, -match, -ne) to see if any of those work....and they don't.
Program Goal: loops until it hits 07:00am
# While the value is 1.
while ($value -ne 2)
{
# Value should be 1 in order to stay in loop.
$value = 1
# Get's the time in 24hr format
$time = get-date -Format HH:mm:ss
# For Debugging; Writes out Time
Write-Output $time
# Creates a Pop-Up Windows that prevents the computer from timing out; runs every 15 minutes.
$wshell = New-Object -ComObject Wscript.Shell
$wshell.Popup("Operation Completed",0,"Done",0x1)
# Causes the Program to wait to send the Enter Keystroke.
Sleep 4
# Sends the Enter Keystroke.
$wshell.sendkeys('~')
# Causes the Program to wait to send the Enter Keystroke in seconds (900sec = 15 Minutes).
Sleep 4
# If Condition; If the time is over 2am then the program quits.
If ($time -eq "02:03:00")
{
# While Loop End Condition
$value = 2
# "Debugging Output"
Write-Output $value
Write-Output $time
}
Else
{
# While Loop Condition
$value = 1
# "Debugging Output"
Write-Output $value
Write-Output $time
}
}
# "Debugging Output"
Write-Output "End"
Write-Output $time
Write-Output $value

Answer 1

The chances are really low that your if-statement will become true. Because your while loop takes at least 8 (2x Start-Sleep and other work) seconds until a new beginning. That means the $time variable will probably never be exactly 02:03:00. In this case I would not go for the exact time. Instead I would check if it's 02:03:00 or later. Try that:
$time = Get-Date
if ($time -ge (Get-Date -Hour 02 -Minute 03 -Second 00))
{
}

Answer 2

This condition should do the work:
if ((Get-Date) -gt (Get-Date -Hour 7 -Minute 0 -Second 0)) {
# While Loop End Condition
$value = 2
# more actions
}
It's comparing the current time with the DateTime object with current day, but time set to 07:00:00.
Keep in mind two things:
It will allow the loop to run only between midnight and 7AM. If you want to start the script the day before you need to adjust the conditions.
It might be more readable to not use if, but put the condition directly in while() like this:
while ((Get-Date) -lt (Get-Date -Hour 7 -Minute 0 -Second 0)) {
# do something
}
Currently, you're checking for exact time, so in theory the end condition might be met, However, if it hits that specific line one second before/after, it won't stop the loop.

Finished Code (at least this version of it anyhow). Appreciate the help too :)!
