When I check a transaction in Electrum and i compare the data with blockchain.info I see that there is a different timestamp. The transaction in Electrum seems to have happened later in time and on blockchain.info it seemed to have happened earlier.
---snip---
Could it be that blockchain.info registers a transaction when it first appeared on the network (with 0 confirmations) and Electrum registers a transaction after 6 confirmations?
Received Time 2018-05-06 23:20:30
Included In Blocks 521531 ( 2018-05-06 23:21:37 + 1 minutes )
above is taken from one of transactions included in block #521531 displayed by blockchain.info
when you look for
actual transaction time, you should look at the
"Included In Blocks" time which essentially is
block timestamp the "Received Time" is when the transaction was received/seen first time on the network for historical data
most explorers show block timestamp in UTC time, a few automatically convert it to local time of the viewers
that
"+/- 2 hours" is an offset from
node-local UTC and not simply
local time zone people might misunderstood the offset time without reading more info on that link
