Now that DST has come again (sigh), I have a question about the digital clocks in your insulin pumps…
How accurate is your clock?
I have a MM 630g pump. I set it against my cell phone, as that’s generally the most accurate time piece anyone usually has access to. About once a quarter, I’ll adjust it, because it’s off by 3 to 5 minutes. I never really thought about this before… I just made the correction every time we did DST and usually 1 or 2 more times kind of at random throughout the year.
Is that a weird amount of clock drift? Should we expect pumps to have clocks that drift this much? (My previous MM was a 5xx series, and it was no better at keeping accurate time.)
This is not something that worries me or that I think is a technical problem. That kind of drift shouldn’t have any real impact on my insulin therapy. Or at least, not any amount that isn’t lost in the general “noise” of imperfect biological systems.
This is more just curiosity.
