Ah, that actually makes sense. Ruby and Weiss both used their Semblances at the same time, and Ruby merely shot Crescent Rose to keep up the momentum.

Though, the haste (clock) glyph definitely has nothing to do with Blake's Semblance, or even Blake at all, since Weiss can use it by herself. I'm actually fairly certain that the haste glyph is actually yellow (lightning) Dust mixed in with her glyph, since she shot a yellow streak from Myrtenaster in order to make that glyph in Painting the Town.

When she uses ice with a glyph, she's using her glyph to move the dark blue (ice) Dust the way she wants it to go in order to shape the ice the way she wants it.
