I'm just wondering if there is a method I can use for undertaking this where I don't lose any data?
I stayed up till 3am last night in order to change my DT80 clock back to 2am when daylight savings ended. One mistake I feel I made was not downloading the data I had collected before I changed the clock. Anyway, when I did change the clock & download the data, I noticed the following:
* I lost all the data for the previous hour in my 1 minute log, ie when I changed the clock back to 2.03am (at 3.03am EDST), all my 1min data from the period 2.03am - 3.03am EDST had vanished & the log began again at 2.03am;
* I lost all the data for the next hour in my 10min data log - that's right, this log didn't begin again till after the clock again ticked over to 3am.
* My 1 hour log however remained unaffected.
