I have scripts that use the following commands to format the time value as follows:

Now(currenttime)
Format(currenttime,"hhmm",currenttimef)

The problem is that about 5% of the time I run the script the value in CURRENTIMEF comes out as "0000" instead of the real time. The other 95% of the time it works perfectly. Any clue what could cause this?

BTW, I've tried the macro command @T"hhmm" and it does not seem to have this problem. I'm planning to change my scripts to use the macro unless you can offer a cause/solution. Thanks!

0000 is valid value! For example time 0 hours 0 minutes and 15 seconds after
calling Format("00:00:15","hhmm",currenttimef)
will return "0000"

Yes...I realize that is a valid time, however, this is occurring at several different times other than midnight, i.e. running a script at 4:25pm sometimes will return a value of "0000".

Just my two cents, try converting to hh:mm and then removing the ":"
For example:
Format(time_variable, "hh:mm", string_variable)
Replace(string_variable, 3, 1, "", string_variable)
