The TSP usually announces the TSP share price around 7 pm. eastern time. It's not ALWAYS prompt, but generally is about then. The first place that usually gets updated is the audio recording on the phone in line. Then, within ten minutes or so on most days, that's followed by the TSP posting the actual share prices on the TSP website.
Tom comes in and posts the updated prices sometime after that- depending on what he's doing that day. The Auto-Tracker usually gets updated somewhat later in the evening when Tom gets a chance.
The TSP updates the actual individual account balance information in the overnight session. I've seen it updated as early as 1:20 a.m. but most night's it's actually after 6 a.m. the following morning before the revised numbers are available.
That's about the norms these days. No promises by anyone, but that's what you are likely to see.
And welcome aboard.
