Ruby + Ruby 2D, 181 bytes

Uses -rruby2d to autoimport the ruby2d library. Mostly an adaptation of my Swiss flag answer but it seems some time in the last 7 years Ruby 2D decided to stop letting you set x and y to nil. Ruby 2.7+ numbered arguments saves 1 byte over what it would've been on that old version, anyways.

I think it's a little fun that this uses all three options for setting color in this library — a hex code '#003580' is used for the flag stripes, an rgba array [1]*4 == [1,1,1,1] for the background, and a keyword 'black' for the text.

[[110,180,0,0],[30,180,40,0],[110,30,0,50]].map{Rectangle.new y:_3,x:_4,height:_1,width:_2,color:'#003580'}[0].color=[1]*4

The date$ builtin returns something like: Thu Jun 6 11:59:59 2024, hence all the string manipulations. The language is indeed basic in some areas!

Online version

Translation:

When the big page opens, it will show the text "<svg><path d=180v110 /><path d=M0,40h50V0h30v40h100v30H80v40H50V70H0 fill=#005580 />" and, if the current time in milliseconds is greater than 1512511200000, it will show the text "<text y=19>100".

SVG was taken from this answer by th3pirat3 (and Neil, appearently).

This program is written in a new version of Tampio I have been working on. Those of you who know Finnish can see that it is almost readable. I marked the answer as non-competing because this language was published after this challenge.

To run this program, either go to the online version above that contains the compiled JS version of the program or download the compiler from its Github page. To compile the program, run python3 tampio.py -p program.itp >program.html.

Tampio is not a golfing language by any measure, but due to the better svg code, it actually beat Röda... I was a little surprised.

Python 3, 143 141 135 bytes

Uses ANSI escape for colors, uses five spaces or " 100 " as a colored string so that I don't need to specially print "100" somewhere on the flag. Length 5 because of width, because 90/5 == 90//5. The string being used is getting defined in row 1. Then we iterate 55 round (height), on every iteration v is set to string with color [Blue, BrightWhite] and selected index is boolean row<20 or r>34. We multiply that result by 5 again (width dimensions: 25:15:50 so total width is 90). Then we print out v + Blue + Blue + Blue + v + v + Black where v is either Blue or BrightWhite. To clarify printing: width of v is 25 chars, width of Blue (e%44*3) is 15 and width of v*2 is 50. 25+15+50 is 90 which is the width and follows the dimensions required in the task! Quite messy summary but I guess it's better than nothing.

Python 3 with Pillow, 213 212 211 characters (Unix) and 217 216 characters (Portable)

This is the Unix version. I realized after posting that the time returned by time() does not necessarily have its epoch on 1 Jan 1970, so it is not necessarily portable.

b=8402688;from PIL import Image,ImageDraw as d
j=Image.new('RGB',(180,110),~1);r=d.Draw(j);R=r.rectangle

r.text((9,9),'100'*(time.time()>=0x5a273300),0)

r.text((9,9),'100'*(time.gmtime()>(2017,12,5,22)),0)
j.show()

The images are displayed in a window. Really difficult to make it consume less characters. Even time.time returns a float so >0x5a273299 would not be quite so correct, or >0x5a273300 would be off by a microsecond.

Here's the same solution trimmed down to 260 bytes, which assumes your viewing port has the proper 18:11 ratio.

<style>.b{background-color:#003580;position:absolute}.v{left:27.78%;width:16.67%;height:100%}.h{top:36.36%;height:27.27%;width:100%}</style><div class="b v"></div><div class="b h"></div><script>if(Date.now()>1512525600000)document.body.innerHTML+=100;</script>

You can knock a 0 off of the timestamp in either solution to see the "100" appear.
