People often want to have a script wait for a specific time to continue executing. This is usualy done with a loop that checks the current time against the destination time. I thought it would be better to use the current time to calculate a sleep time to get there. Then the Script only has to check the time once.
Function:

Code:

SleepTill(Time) {
ST_Hour:=SubStr(Time, 1 ,2)
ST_Min:=SubStr(Time, 3 ,2)
ST_Sec:=(SubStr(Time, 5 ,2)<>"" ? SubStr(Time, 5 ,2) : "00")
STime:=(((ST_Hour-A_Hour)*60+(ST_Min-A_Min))*60+(ST_Sec-A_Sec))*1000 
STime:=STime<0 ? STime+86400000 : STime
Sleep %STime%
Return % A_Hour ":" A_Min
}

Examples:

Code:

SleepTill(1700)
MsgBox It is Now 5:00PM Time to go home.

MsgBox % "It is Now 30 sec's past "SleepTill(154830)

Modified version that can be used with SetTimer msTill

Edit:Added support for seconds and return time
Edit 2: added Link to Altered form

Why not make a sleep/runat library? SleepBetween, SleepAfter and some repeat parameters e.g. Run at 17:00 every (week)day/week etc...

This is the code I wrote. Same number of lines (and a lot less math), but can use 4 or six digit time and optionally returns the final time.

Code:

; example useage
MsgBox % "It is Now " WaitForTime(0241) " Time to go home."   ; can use 4 digit time
MsgBox % "It is Now " WaitForTime(024130) " Time to go home."   ;  or 6 digit time
WaitForTime(0210)
now := WaitForTime(0210)

WaitForTime(eTime) { 
  eTime := A_YYYY A_MM A_DD SubStr(eTime, 1 ,2) SubStr(eTime, 3 ,2) (SubStr(eTime, 5, 2) ? SubStr(eTime, 5, 2) : "00")
  if (A_Now > eTime) ; if eTime is past, set for tomorrow at eTime
    eTime += 1, day
  TimeToSleep := eTime
  TimeToSleep -= A_Now, seconds
  Sleep, % TimeToSleep * 1000
  FormatTime, current, A_Now, HHmmss ; optional - comment out if you don't need the current time returned
  Return, current
}
}

No, not a typo - sloppy copy & paste (and old eyes). :oops:

Thanks for catching and reporting the error.

Here's something that was posted by Chris himself a while back to run a script at a certain time. It also uses the current time to calculate a waiting time to get there - the Script only has to check the time once.

Instead of Sleep, it uses SetTimer to wait till the calculated time-difference between the scheduled time and the current time.

Thanks jenhafman returning time is a good idea
I thought adding seconds was silly but since you did it I figured why not.
I also changed the math so there arn't so many scary big numbers

arsan good searching I don't think Settimer would work in a functon very well.

You're right. It wasn't meant to be used as a function. It was just a demonstration of a criteria you mentioned - using the current time to calculate a wait time to get there so that the script has to check the time once only.

That's why SetTimer is usually a better solution.

You must post your code so that others may look into it to figure out the problem.

Not really. Sleep causes the script to hang, so it's a pretty obvious problem.

It Should only sleep the current thread. New threads created by SetTimer or Hotkeys should work.
I just tried this

Code:

SetTimer Try, 1000
SleepTill(100100)
MsgBox Hello
Return

a::MsgBox It Works
Esc::ExitApp

Try:
SoundBeep
Return

The Hotkeys worked and so did the SetTimer.

The fact that Sleep waits the specified amount of time before continuing is so basic that I don't think that the poster won't know about it. That's why I wanted to have a look at his code.

Hi I'm author of Sleeper, sorry it's not a very good script and at this time I didn't know concept like scheduler or dispatcher... In fact, Sleeper thread is not famous

However, I think that my script can be customize, must replace the comparison of a_tickcount by a date seems easy...

other link, can be usefull ( it's the wish list) :
