I'd like to change the time of day in SSP, from day to night or night to day. If I'm building something, I don't want to have to set up a bed; if I'm lighting my place, I don't want to have to wait for morning.
I know that in 1.3 or something there was an application called MinecraftTimeChanger that... did what it said on the tin, but it apparently hasn't been updated for 1.5. Is there another editor that can let me change the time values? NBTedit shows an entry for time, but I don't know what to put in the slot. I've heard that MineEdit has a time entry too, but MineEdit just fails to load for me.
