Is there an SMP Server Command to change weather conditions? [duplicate]

The latest version of Minecraft (1.5) brings, among other things, a number of different weather conditions. Most of these annoy me to no end. I tend to spend a lot of time playing on an SMP server, so I'm wondering if at least here, there is a way to effect changes in the weather: maybe through server commands?

Yes, there is.

As of 1.4.2, /weather (operators only) can be used to control the weather server-wide.

/weather clear
/weather rain
/weather thunder

You can also optionally specify the number of seconds, up to a million (that's 11 days and ~14 hours). For example, /weather clear 60 will clear up the weather for 1 minute only.

Also, the /toggledownfall command (also ops only) stops/starts rain or snow on a vanilla server. It was added in a beta 1.9 pre-release.

Bukkit has integrated the commands into it. You need OP but:

/weather sunny <time> 
/weather storm <time> 
/lighting <true/false> 
/thunder <true/false>
