finding a time inside a time range -

i use a timer to tell the server when to start sending me time. 'theoretically' it is supposed to start on-time and look like this

11:22:54 - 11:22:49
11:22:59 - 11:22:54
11:23:04 - 11:22:59
11:23:09 - 11:23:04

etc

where i compare the current time on the left (what just came in) with the time on the right (the time stamp just prior)

but sometimes the server 'hiccups' and i might see this instead


11:22:57 - 11:22:49
11:23:02 - 11:22:57
11:23:08 - 11:22:02
11:23:12 - 11:23:08

or something like that

the server is geared to send out a time stamp every 5 seconds (its minimum) but i need to make a change at :59

basically i need to evaluate the current time stamp and the one just prior and see if my :59 is somewhere either in between or at either end (where it 'usually' but not always is)

something like

"if somewhere in between the current time and the last time a time with :59 seconds can be found

dostuff

end if"
