You can use and distribute this applet freely!
Applet is very flexible. Parameters which can be used in the applet are below: 

<APPLET code=grSaat width=112 height=20>
     <param name=wdth value=16>
     <param name=dir value=Blgrv>
     <param name=slash value="/">
     <param name=d0 value=0blgrv.gif>
     <param name=d1 value=1blgrv.gif>
     <param name=d2 value=2blgrv.gif>
     <param name=d3 value=3blgrv.gif>
     <param name=d4 value=4blgrv.gif>
     <param name=d5 value=5blgrv.gif>
     <param name=d6 value=6blgrv.gif>
     <param name=d7 value=7blgrv.gif>
     <param name=d8 value=8blgrv.gif>
     <param name=d9 value=9blgrv.gif>
     <param name=col value=Cblgrv.gif>
     <param name=backR value=0>
     <param name=backG value=0>
     <param name=backB value=0>
     <param name=correction value=0>
</APPLET> 

wdth    : Witdh of digit images.
dir       : Directory of image files
slash   : Slash type ( / or \ )
d0..d9 : Name of the digit files
col      : Name of colon file
correction  : Correction value for hour value (must be - or + integer)!
backR, backG, backB  : Red, green ande blue component of the back ground color.

Default values are exist and set to value of images which is given with the applet. If you don't use any parameters, applet use below values and can be seen above!
wdth = 16
dir = kasa
slash = /
d0 = zero.gif
d1 = one.gif
d2 = two.gif
d3 = three.gif
d4 = four.gif
d5 = five.gif
d6 = six.gif
d7 = seven.gif
d8 = eight.gif
d9 = nine.gif
col = There is no colon value and image. Applet use half of image width gap instead of colon as default.
backR, backG, backB = 0 (all, black)
correction = 0

Important: Height of applet must be equal height of digit images. Width of applet depends on existance of colon image. If you use colon, applet width must be 8*(width of digit images). If you don't use, width must be 7*(width of digit images).
Example:
Image width = 20 pixel
with colon,        applet width = 160
without colon,    applet width = 140
