For a data match to occur, both QSOs date/time (in UTC) must be within 30 minutes of each other.
Here's the link to the LOTW info that spells out what constitutes a data match. https://p1k.arrl.org/lotw/faq#datamatch

The ARRL does a nice job of spelling out the parameters here: http://www.arrl.org/files/file/LoTW%20Instructions/N5JB.pdf
The band that matters ( according to the ARRL ) is the band you transmit on, not the band you receive on.
Here is the data you need to log the contact and have it count in LOTW
CALL:6 [The Station You Worked] <QSO_DATE:8> [YYYYMMDD] <TIME_ON:6> [HHMMSS] in utc BAND:4 [The band you transmitted on] MODE:3 [SSB, CW, FM, etc.] <PROP_MODE:3>SAT <SAT_NAME:4> [The bird you used]
<EOR>
Please note it is VERY unforgiving as far as entries go. Things must be spelled correctly! The [] above should not be included. I have yet to hear the exact allowable clock difference, but I'm sure it is several minutes at least.

Hi All,
I am trying to get myself going on LoTW, and I need to know what the generally excepted parameters are for QSO information.
In my logbook (HRD), what should I put for the freq. (2m, 440)?
What happens if my log entry is one minute off of stations B’s entry (1906z versus 1905z) – will they match up?
What should my mode be set at (FM, SAT)?
Other than date, time, call, mode, sent RST, rcvd RST, band and name (op name), is there anything that needs to be added to it when I go to upload? This was the default LoTW selection for HRD, so I am assuming it is correct.
I can’t think of any other questions at the moment, but any other helpful tips for getting it started would be appreciated.
73!
