Sounds like you want to group by ID and then convert to a dictionary, so that you end up with one dictionary entry per ID:
var dictionary = entries.GroupBy(x => x.ID)
.ToDictionary(g => g.Key,
// Find the earliest time for each group
g => g.Min(x => x.Time));
Or:
// Group by ID, with each value being the time
var dictionary = entries.GroupBy(x => x.ID, x => x.Time)
// Find the earliest value in each group
.ToDictionary(g => g.Key, g => g.Min())
