    synctex: pass correct timestamp for sync_view()
    
    It's important to pass the correct timestamp, because if
    GDK_CURRENT_TIME is used, sometimes Evince is not shown directly, but a
    notification appears: "Document Viewer [...] is ready", so it was a bit
    annoying to click on the notification to show Evince.
    
    Now it should be fixed.
